The board is produced in variants fitted with different displays. Move
the current RGB panel to a device tree overlay and add one for the LVDS
variant, so that the board dts describes only what is common and each
display gets its own overlay.

Changes in v2:
- Keep the full cs-gpios in the board dts, the overlay only adds the
  panel node. Suggested by Sashiko.
