board: toradex: add colibri imx8qxp 2gb wb it v1.0b module support

This commit adds initial support for the Toradex Colibri iMX8QXP 2GB WB
IT V1.0B module. Unlike the V1.0A early access samples exclusively
booting from SD card, 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 and MMC/SD card
- Ethernet
- GPIOs
- I2C

Unfortunately, there is no USB functionality for the i.MX 8QXP as of
yet.
