Subject: dt-bindings: display: Convert Allwinner DSI to a schema

The Allwinner SoCs have a MIPI-DSI and MIPI-D-PHY controllers supported in
Linux, with a matching Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.
