Marcel Ziswiler 7d1a10659f board: toradex: add verdin am62 support
This adds initial support for the Toradex Verdin AM62 Quad 1GB WB IT
V1.0A module and subsequent V1.1 launch configuration SKUs. They are
strapped to boot from their on-module eMMC. U-Boot supports booting
from the on-module eMMC only, DFU support is disabled for now due to
missing AM62x USB support.

The device trees were taken straight from Linux v6.5-rc1.

Boot sequence is:
SYSFW ---> R5 SPL (both in tiboot3.bin) ---> ATF (TF-A) ---> OP-TEE
  ---> A53 SPL (part of tispl.bin) ---> U-boot proper (u-boot.img)
