[PATCH 4/6] drm/panel: simple: Add support for Banana Pi 7" S070WV20-CT16 panel

[Chen-Yu Tsai]

This panel is marketed as Banana Pi 7" LCD display. On the back is
a sticker denoting the model name S070WV20-CT16.

This is a 7" 800x480 panel connected through a 24-bit RGB interface.
However the panel only does 262k colors.
