Most of the Allwinner MIPI DSI controllers are supply with VCC-DSI pin. which need to supply for some of the boards to trigger the power. So, document the supply property so-that the required board can eable it via device tree.

It looks like the VCC power rail is found on all the Allwinner SoCs, so it should be made mandatory. Maxime -- Maxime Ripard, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
