[PATCH v11 4/7] dt-bindings: sun6i-dsi: Add VCC-DSI supply property

[Jagan Teki]

Allwinner MIPI DSI controllers are supplied with SoC DSI
power rails via VCC-DSI pin.

Some board still work without supplying this but give more
faith on datasheet and hardware schematics and document this
supply property in required property list.
