From: Sam Ravnborg sam@ravnborg.org

To complement panel-simple.yaml, create panel-simple-dsi.yaml. panel-simple-dsi-yaml are for all simple DSP panels with a single power-supply and optional backlight / enable GPIO / reset GPIO.

Migrate panasonic,vvx10f034n00, orisetech,otm8009a and raydium,rm68200 over to the new file.

The objectives with one file for all the simple DSI panels are: - Make it simpler to add bindings for simple DSI panels - Keep the number of bindings file lower - Keep the binding documentation for simple DSI panels more consistent
