ucm2: IO-Boards: Toradex: verdin: Add support for Toradex

Add support for the Toradex Verdin Development carrier board, using the
NAU8822 audio codec.

This is a carrier board for the Verdin family, where any Verdin SoM
(NXP, TI...) can be connected to it, therefore this is being added to
the IO-Boards instead of a specific hardware vendor.
