Purpose is to simplify the STI driver:

Apply the plane depth when the plane is updated.
If the depth is different from the previous plane update,
the register controlling the plane depth is cleaned and updated
with the new depth.

No big bang, only adapt some functions to new call order.
v2: Use dpms and page flip atomic helpers

High Quality Video Data Plane is hardware IP dedicated
to video rendering. Compare to GPD (graphic planes) it
have better scaler capabilities.
HQVDP use VID layer to push data into hardware compositor
without going into DDR. From data flow point of view HQVDP
and VID are nested so HQVPD update/disable VID.

Create the driver itself and make it register all the sub-components.
Use GEM CMA helpers for buffer allocation.
