arm64: dts: imx8mm-verdin: Add yavia carrier board

Add new carrier board device tree Yavia for the Verdin iMX8M Mini SoM.

Yavia is a compact carrier board providing easy access to the most
common features of the Verdin family. The intended use of the carrier
board is application software development. The board is compatible with
all current and future Verdin SoMs.
