Add support for the gmac ethernet interface to pinctrl. This hardcodes
the setup to match that of the firefly and Radxa Rock2 boards, using the
RGMII phy mode for gmac interface and GPIO4B0 as the phy reset GPIO.

According to rk3288 spec, the pwm register order is:
PWM_PWM0_CNT,
PWM_PWM0_PERIOD_HPR,
PWM_PWM0_DUTY_LPR,
PWM_PWM0_CTRL
but the source code's order is:
struct rk3288_pwm {
u32 cnt;
u32 duty_lpr;
u32 period_hpr;
u32 ctrl;
};
So, correct it here. It is the same as RK3399.

This commit enables the RK3399 HDMI TX, which is very similar to the
one found on the RK3288. As requested by Simon, this splits the HDMI
driver into a SOC-specific portion (rk3399_hdmi.c, rk3288_hdmi.c) and
a common portion (rk_hdmi.c).
Note that the I2C communication for reading the EDID works well with
the default settings, but does not with the alternate settings used on
the RK3288... this configuration aspect is reflected by the driverdata
for the RK3399 driver.
Having some sort of DTS-based configuration for the regulator
dependencies would be nice for the future, but for now we simply use
lists of regulator names (also via driverdata) that we probe.

To prepare for adding the RK3399 VOP driver (which shares most of its
registers and config logic with the RK3228 VOP), this change refactors
the driver and splits the RK3288-specific driver off.
The changes in detail are:
- introduces a data-structure for chip-specific drivers to register
features/callbacks with the common driver: at this time, this is
limited to a callback for setting the pin polarities (between the
VOP and the encoder modules) and a flag to signal 10bit RGB
capability
- refactors the probing of regulators into a helper function that
can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
used by the chip-specific drivers to provide base addresses to
the common driver
- uses a callback into the chip-specific driver to set pin polarities
(replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate
help function withint the common driver

RK3288_TXCLK_DLY_ENA_GMAC_ENABLE, in GRF_SOC_CON3, is supposed to be bit
0xe and not 0xf. Otherwise, it is RGMII RX clock delayline enable and
introduces random delays and data lose.
This commit fixes the issue by replacing RK3288_TXCLK_DLY_ENA_GMAC_ENABLE
with the right shift.

In rk3328, some function pin may have more than one choice, and muxed
with more than one IO, for example, the UART2 controller IO,
TX and RX, have 3 choice(setting in com_iomux):
- M0 which mux with GPIO1A0/GPIO1A1
- M1 which mux with GPIO2A0/GPIO2A1
- usb2phy which mux with USB2.0 DP/DM pin.
We should not decide which group to use in pinctrl driver,
for it may be different in different board, it should goes to board
file, and the pinctrl file should setting correct iomux depends on
the com_iomux value.

The RK3399-Q7 ("Puma") SoM exposes UART0 as the Qseven UART (i.e. the
serial line available via standardised pins on the edge connector and
available on a RS232 connector).
To support boards (such as the RK3399-Q7) that require UART0 as a
debug console, we match CONFIG_DEBUG_UART_BASE and add the appropriate
iomux setup to the rk3399 SPL code.
As we are already touching this code, we also move the board-specific
UART setup (i.e. iomux setup) into board_debug_uart_init(). This will
be called from the debug UART init when CONFIG_DEBUG_UART_BOARD_INIT
is set.
As the RK3399 needs to use its board_debug_uart_init() function, we
have Kconfig enable it by default for RK3399 builds.
With everything set up to define CONFIG_BAUDRATE via defconfig and
with to have the SPL debug UART either on UART0 or UART2, the configs
for the RK3399 EVB are then update (the change for the RK3399-Q7 is
left for later to not cause issues on applying the change).

The GMAC in the RK3399 is very similar to the RK3288 variant (i.e. it
is a Designware GMAC core and requires similar configuration as the
RK3288 to switch it to RGMII and set up the TX/RX delays for Gigabit).
The key difference is that the register offsets (within the GRF block)
and bit-offsets (within those registers) used to hold the configuration
differ between the various RK32/33 CPUs.
This change refactors the gmac_rockchip.c driver to use a function
table (selected via driver_data) to factor out these differences. Each
function's implementation then matches the underlying processor.
Some collateral changes are needed in the definitions describing the
bits and offsets in the GRF are needed to prefix each set of symbolic
constants with the SoC name to avoid name clashes... and in doing so,
the shifts for masks and constants have been moved into the header
files for readability (and to make it easier to stay below 80 chars).

The armclk starts in slow mode (24MHz) on the rk3188, which makes the whole
startup take a lot of time. We therefore want to at least move to the safe
600MHz value we can use with default pmic settings.
This is also the freqency the proprietary sdram-init leaves the cpu at.
For boards that have pmic control later in u-boot, we also add the option
to set the maximum frequency of 1.6GHz, if they so desire.

The SPL binary needs to be prefixed with the boot magic ('RK33' for
the RK3399) on the Rockchip platform and starts execution of the
instruction word following immediately after this boot magic.
This poses a challenge for AArch64 (ARMv8) binaries, as the .text
section would need to start on the odd address, violating natural
alignment (and potentially triggering a fault for any code that
tries to access 64bit values embedded in the .text section).
A quick and easy fix is to have the .text section include the 'RK33'
magic and pad it with a boot0 hook to insert 4 bytes of padding at the
start of the section (with the intention of having mkimage overwrite
this padding with the appropriate boot magic). This avoids having to
modify the linker scripts or more complex logic in mkimage.

The sdram controller blocks are very similar to the rk3288 in utilizing
memory scheduler, Designware uPCTL and Designware PUBL blocks, only
limited to one bank instead of two.
There are some minimal differences when setting up the ram, so it gets
a separate driver for the rk3188 but reuses the driver structs, as there
is no need to define the same again.
More optimization can happen when the modelling of the controller parts
in the dts actually follow the hardware layout hopefully at some point
in the future.
