dt-bindings: display: Convert Allwinner display pipeline to schemas 
The Allwinner SoCs have a display engine composed of several controllers
assembled differently depending on the SoC, the number and type of output
they have, and the additional features they provide. A number of those are
supported in Linux, with the matching bindings.

Now that we have the DT validation in place, let's split into separate file
and convert the device tree bindings for those controllers to schemas.

TCON can have 1 or 2 channels, usually with the
first channel being used for the panels interfaces
(RGB, LVDS, etc.), and the second being used for the
outputs that require another controller (TV Encoder,
HDMI, etc.).
If that property is present, specifies the TCON
channel the endpoint is associated to. If that
property is not present, the endpoint number will be
used as the channel number.
