arm: dts: mediatek: add UFS variant of Genio 520/720 EVK

Add a devicetree overlay and UFS variants of the Genio 520 and Genio 720
EVK devicetree targets. There are dip switches and jumpers on the EVK
that disconnect the eMMC and connect the UFS instead. The overlay
adjusts the devicetree for this.
