[PATCH 1/6] dt-bindings: display: panel: Add another panel for RG35XX Plus (Rev6)

This is a display panel used in the recent revision of the Anbernic
RG35XX Plus, a handheld gaming device from Anbernic.
It is 3.45 inches in size (diagonally) with a resolution of 640x480.

It has the same interface (pins and connector) as the panel of the former
revision of RG35XX Plus, but they differ in their init-sequence. So add
it as a new panel.
