This is the only place where i.MX8M code does SMCCC call, remove it.
The output has little value as it prints some part of commit ID, and
worse, if there is no SMC handler installed, the code outright hangs
or crashes the system.
By removing this one instance of SMCCC call, U-Boot no longer depends
on SMC handlers and can boot without hanging in any case. If there is
a need to dump this commit ID, use CMD_SMC instead and do 'smc' call
from U-Boot shell or scripts instead of hard-coding SMCCC dependency
into architecture code. This particular code can be replaced by:
=> smc 0xc2000003 0 0 0 0 0 0

The FlexSPI NOR boot offset does not require any special handling,
the image_offset is correct in either case (0x1000 for FlexSPI NOR
and 0x8000 for SD/eMMC) and the offset of u-boot.itb from the start
of flash.bin is always 0x58000 on MX8MN/MX8MP, which matches the
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR * 512 - 0x8000 in case
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR=0x300, which is always the
case on MX8MN/MX8MP.
The CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR is really overloaded in
case of the MX8MN/MX8MP, but fixing that needs additional plumbing.

Wait 1ms before issuing the first MRS command to write DDR3 Mode
registers.
There is a requirement to wait a minimum time before issuing command to
the DDR3 device, according to the JEDEC standard this time is 500us
(after RESET_n is de-asserted until CKE becomes active) + tXPR (Reset
CKE Exit time, maximum value 360ns).
It seems that for some reason this is not enforced by the MMDC
controller.
Without this change we experienced random memory initialization failures
with about 2% boot failure rate on specific problematic boards, after
this change we were able to do more than 10.000 power-cycle without a
single failure.

The current DDR write level calibration routine always overwrite
the ralat/walat fields to their maximum value, just save
the existing values at the beginning of the calibration routine
and restore it at the end.
In case the delay is estimated by the user to be more than one cycle the
walat should be configured according to that, this is not
automatically done. From the i.MX6 RM:
The user should read the results of the associated delay-line at
MPWLDECTRL#[WL_DL_ABS_OFFSET#] and in case the user estimates that the
reasonable delay may be above 1 cycle then the user should indicate it at
MPWLDECTRL#[WL_CYC_DEL#]. Moreover the user should indicate it in
MDMISC[WALAT] field. For example, if the result of the write leveling calibration
is 100/256 parts of a cycle, but the user estimates that the delay is above 2 cycles
then MPWLDECTRL#[WL_CYC_DEL#] should be configured to 2, so the total
delay will be 2 and 100/256 parts of a cycle
Probably it would just possible to not overwrite the mdmisc register in
the first place, since this is not present in the write_level_calib() example
in NXP AN4467 nor in the i.MX6 RM (44.11.6.1 Hardware Write Leveling

A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.
The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).
Platforms can overwrite the weak definition of spl_mmc_boot_mode() to
determine where to load U-Boot proper from.
For most of them this is a trivial decision based on Kconfig variables,
but it might be desirable the probe the actual device to answer this
question.
Pass the pointer to the mmc struct to that function, so implementations
can make use of that.
Compile-tested for all users changed.
