Add a basic device-tree (mt8395-genio-1200-evk-ufs.dts) in order to be able to use UFS storage as the main storage on Genio 1200 EVK board.
This board is the origin Genio 1200 EVK already mounted two main storages, one is eMMC, and the other is UFS. The system automatically prioritizes between eMMC and UFS via BROM detection, so user could not use both storage types simultaneously. As a result, mt8395-evk-ufs must be treated as a separate board.
It use mt8395-genio-common.dtsi file to use common definitions.
