drm/panel: add Raydium RM67200 panel driver

The Rockchip W552793DBA-V10 display/touchscreen board contains a
Wanchanglong W552793BAA panel, which in turn is using a Raydium
RM67200 MIPI-DSI controller. Add a DSI panel driver for it.

The W552793BAA panel init sequence has been taken from the RK3588
EVB1 vendor kernel devicetree.
