For now, the existing SPL MXS NAND driver only supports to identify
ONFi-compliant NAND chips. In order to allow identifying
non-ONFi-compliant chips add `mxs_flash_full_ident()` which uses the
`nand_get_flash_type()` functionality from `nand_base.c` to lookup
for supported NAND chips in the chip ID list.
For compatibility reason the full identification support is only
available if the config option `CONFIG_SPL_NAND_IDENT` is enabled.
The lookup was tested on a custom i.MX6ULL board with a Toshiba
TC58NVG1S3HTAI0 NAND chip.

The existing `mxs_flash_ident()` is limited to identify ONFi compliant
NAND chips only. In order to support non-ONFi NAND chips refactor the
function and rename it to `mxs_flash_onfi_ident()`.
A follow-up patch will add `mxs_flash_full_ident()` which allows to use
the chip ID list to lookup for supported NAND flashs.

`nand_get_flash_type()` allows identification of supported NAND flashs.
The function is useful in SPL (like mxs_nand_spl.c) to lookup for a NAND
flash (which does not support ONFi) instead of using nand_simple.c and
hard-coding all required NAND parameters.

The PFUZE3000 uses registers addresses up to 0xff.
The DM pfuze100 driver supports both pfuze100 and pfuze3000. Allow it
to use the device type to return the correct number of registers.
Also rename the too generic PMIC_NUM_OF_REGS enumeration value for
pfuze3000 to match the other "PFUZE3000_" prefixed enumerations and the
pfuze100 enumeration value PFUZE100_NUM_OF_REGS.

Add support for specified ECC strength/size using device tree
properties nand-ecc-strength/nand-ecc-step-size.
This aligns behavior with the mainline driver, such that:
- If fsl,use-minimal-ecc is requested it will use data from
data sheet/ONFI. If this is not available the driver will fail.
- If nand-ecc-strength/nand-ecc-step-size are specified those
value will be used.
- By default maximum possible ECC strength is used

Calculate BCH geometry at start and store the information in
a structure. This avoids recalculation on every page access
and allows to calculate ECC relevant information in one place.
This patch does not change ECC layout or driver behavior in
any way.
The patch aligns the driver somewhat with the Linux GPMI NAND
driver which drives the same IP.

In Linux, the clock rate of the UART is given by the clock driver.
If you try to follow that in U-Boot, you would end up with adding
more u-boot,dm-pre-reloc properties, and also the clock driver would
be too big for SPL, which is used for UniPhier ARMv7 platform.
The current solution is to add 'clock-frequency' property to the
UART nodes, but it does not exist in the DT files in Linux. I do
not want to let DT diverge for U-Boot.
Check the SoC compatible and set the clock rate according to it.
This will be helpful to sync DT between Linux and U-Boot.

Do not stop the clock in the start callback in case of failure, keep
them running to also keep the PHY running. The failure could be ie.
PHY failing to negotiate link and if the clock get shut down, another
attempt at bringing the link up would fail. The clock right now are
started in probe function and stopped in remove function, which is
the correct behavior.

This issue was found when OF_LIVE was enabled that there are scrambled

Chip ID: zu3eg
Watchdog: Started��j� sdhci@ff160000: 0, sdhci@ff170000: 1

I found a solution for this problem exactly the same as I found later in
serial_msm fixed by:
"serial: serial_msm: initialize uart only before relocation"
(sha1: 7e5ad796bcd65772a87da236ae21cd536ae3a4d2)

sent and _uart_zynq_serial_init() resets TX fifo even in the middle of
