cb61b2fb2b ARM: imx: Get rid of only i.MX8M SMCCC arch call
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.

6924bc7ca2 imx8mm-cl-iot-gate: Retrieve the DDR type from EEPROM
Currently, the DDR type is retrieved by iteracting inside an array
of possible DDR types.

This may take saveral attempts, which slows the overall U-Boot process
and does not provide a good user experience:

Improve the boot time by retrieving the correct DDR information from
the EEPROM:

Based on the original code from Compulab's U-Boot.

Tested on a imx8mm-cl-iot-gate board populated with 4GB of RAM.

0bb304e363 imx8mm-cl-iot-gate: Add SPL EEPROM support
imx8mm-cl-iot-gate supports multiple DDR sizes and models.

The DDR type can be retrieved from the EEPROM, so add SPL code
that can be used to get the DDR information.

Based on the original code from Compulab's U-Boot.
