board: toradex: add verdin imx8mm 2gb wb it v1.0a module support

This commit adds initial support for the Toradex Verdin iMX8MM 2GB WB IT
V1.0A module. They are now strapped to boot from eFuses which are
factory fused to properly boot from their on-module eMMC. U-Boot
supports either booting from the on-module eMMC or may be used for
recovery purpose using the universal update utility (uuu) aka mfgtools
3.0.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Gigabit Ethernet
- GPIOs
- I2C
- USB_1 peripheral: fastboot or ums
- USB_2 host: USB mass storage

To prepare the program image for eMMC fastboot using imx-mkimage and
subsequently flash it using U-Boot proceed as follows:

cd imx-mkimage/
make SOC=iMX8MM flash_evk_emmc_fastboot

load mmc 1:1 $loadaddr flash.bin
setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
mmc dev 0 1
mmc write ${loadaddr} 0x2 ${blkcnt}

To prepare the program image for use with USB recovery aka serial
downloader using imx-mkimage and subsequently download using uuu
with an uuu.auto script proceed as follows:

cd imx-mkimage/
make SOC=iMX8MM flash_evk

uuu_version 1.3.34

SDP: boot -f flash.bin
CFG: SDPU: -vid 0x0525 -pid 0xb4a4
SDPU: delay 1000
SDPU: write -f flash.bin -offset 0x57c00
SDPU: jump

Fusing i.MX 8MM SoC and configuring eMMC for fastboot (already done
during manufacturing):

fuse prog 1 3 0x100020d6 (BT_FUSE_SEL, eMMC boot, SD1, fast boot, 4-bit DDR, high speed, 1.8V)
fuse prog 2 2 0x00000001 (enable boot ack)

mmc bootbus 0 1 0 2 (4-bit, reset bus width, DDR)
mmc partconf 0 1 1 0 (booting from boot area partition 1, send acknowledge)

SD manufaccture boot:

SD manufacture boot only works as long as the module is un-fused and
SD_1_PWR_EN is bypassed on the carrier board.

cd imx-mkimage/
make SOC=iMX8MM flash_evk

sudo dd if=iMX8M/flash.bin of=/dev/mmcblk0 bs=1024 seek=33
