Subject: [PATCH 2/5] dt-bindings: media: sun6i: Add vcc-csi supply property

Most of the Allwinner A64 CSI controllers are supply with
VCC-PE pin. which need to supply for some of the boards to
trigger the power.

So, document the supply property as vcc-csi so-that the required
board can eable it via device tree.

Used vcc-csi instead of vcc-pe to have better naming convention
wrt other controller pin supplies.
