PMU is the power management unit and GRF is the general register file. Both
are heavily used in U-Boot. Add header files with register definitions.

Add header files for the peripherals and clocks supported on Rockchip

The Rockchip boot ROM requires a particular file format for booting from SPI.
It consists of a 512-byte header encoded with RC4, some padding and then up
to 32KB of executable code in 2KB blocks, separated by 2KB empty blocks.
Add support to mkimage so that an SPL image (u-boot-spl-dtb.bin) can be
converted to this format. This allows booting from SPI flash on supported
machines.

Rockchip SoCs require certain formats for code that they execute, The
simplest format is a 4-byte header at the start of a binary file. Add
support for this so that we can create images that the boot ROM understands.

All devices should bind without error. But when they don't, they can cause
driver model init to fail. A real situation where this can happen is when
there is a missing uclass.
Add a debug() call to dm_scan_fdt_node to make this easier to track.

When a uclass definition is missing, no drivers in that uclass can operate.
This can happen if a board has a strange collection of options (e.g. the
driver is enabled but the uclass is not).
Unfortunately this is very confusing at present. Starting up driver model
results in a -ENOENT error, which is pretty generic. Quite a big of digging
is needed to get to the root cause.
To help with this, change the error to a very strange one with no other
users in U-Boot. Also add a debug message.

My original pinctrl patch operating using a peripheral ID enum. This was
shared between pinmux and clock and provides an easy way to specify a device
that needs to be controlled, even it is does not (yet) have a driver within
driver model.
Masahiro's new simple pinctrl gets around this by providing a
set_state_simple() pinctrl method. By passing a device to that call the
peripheral ID becomes unnecessary. If the driver needs it, it can calculate
it itself and use it internally.
However this does not solve the problem for peripheral clocks. The 'pure'
solution would be to pass a driver to the clock uclass also. But this
requires that all devices should have a driver, and a struct udevide. Also
a key optimisation of the clock uclass is allowing a peripheral clock to
be set even when there is no device for that clock.
There may be a better way to achive the same goal, but for now it seems
expedient to add in peripheral ID to the pinctrl uclass. Two methods are
added - one to get the peripheral ID and one to select it. The existing
set_state_simple() is effectively the union of these.

There is a hole in shadow registers address map of size 0x100
between bank 5 and bank 6 on iMX6QP, iMX6DQ, iMX6SDL, iMX6SX and iMX6UL.
Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading the fuses,
we should account for this hole in address space.
Similar hole exists between bank 14 and bank 15 of size
0x80 on iMX6QP, iMX6DQ, iMX6SDL and iMX6SX.
Note: iMX6SL has only 0-7 banks and there is no hole.
Note: iMX6UL doesn't have this one.
When reading, we use register offset, so need to account for holes
to get the correct address.
When writing, we use bank/word index, there is no need to account
for holes, always use bank/word index from fuse map.

On some CM-FX6 modules U-Boot attempts to configure the usb0 controller in
device mode, which renders it unavailable:
USB0: Port not available.
and also causes usb stop to report an error
EHCI failed to shut down host controller.
This happens mostly on MX6 Dual based modules, and is caused by the USBPHY_CTRL
register reporting USBPHY_CTRL_OTG_ID to be 1, even when it is pulled down.
Since we do not support device mode in cm-fx6 u-boot, force all controllers to
be configured as hosts.

2. Introduce a structure mx6_lpddr2_cfg, most entrys are same to
mx6_ddr3_cfg, but still keep it a single one for easy to choose

To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg
to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper.
The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg
when ddr_type is for DDR3. Later we can use ddr_type to initialize
MMDC for LPDDR2.
Initialize ddr_type for different boards which enable SPL.
