[PATCH v2 2/2] dt-bindings: one file of all simple DSI panels

[Sam Ravnborg <sam@xxxxxxxxxxxx>]

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.

Migrate panasonic,vvx10f034n00 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

+description: |
+  This binding file is a collection of the DSI panels that
+  requires only a single power-supply.
+  There are optionally a backlight and an enable GPIO.
+  The panel may use an OF graph binding for the association to the display,
+  or it may be a direct child node of the display.
+
+  If the panel is more advanced a dedicated binding file is required.
