board: toradex: add verdin imx8m plus support

This adds initial minimal support for the Toradex Verdin iMX8M Plus Quad
4GB WB IT V1.0A and Toradex Verdin iMX8M Plus Quad 2GB V1.0A modules.
They are strapped to boot from eFuses which are factory fused to
properly boot from their on-module eMMC. U-Boot supports booting from
the on-module eMMC or, if the recovery button/pin is asserted, via USB
serial download aka SDP support.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet (but only 2nd one available on the Verdin Development board)
- GPIOs
- I2C

Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.
