[PATCH v11 3/4] arm64: dts: imx8mp-skov-revc: convert jutouch and tian to overlays

The i.MX8MP Skov RevC jutouch 10" and Tian 7" variants are pretty
similar, apart from the Display and touch controller.
Move the common bindings to imx8mp-skov-revc-touch.dts and convert both
variants to use overlays applied on this base version.
