Atomic update should never fail. Thus all checks must be done in
the atomic_check function for each plane (gdp, hqvdp and cursor).

Done with coccinelle for the most part. It choked on
msm/mdp/mdp5/mdp5_plane.c like so:
"BAD:!!!!! enum drm_plane_type type;"
No idea how to deal with that, so I just fixed that up
by hand.
Also it thinks '...' is part of the semantic patch, so I put an
'int DOTDOTDOT' placeholder in its place and got rid of it with
sed afterwards.
I didn't convert drm_plane_init() since passing the varargs through
would mean either cpp macros or va_list, and I figured we don't
care about these legacy functions enough to warrant the extra pain.

The way to load the HQVDP firmware has been updated.
HQVDP firmware is now loaded the first time an HQVDP plane is used and
no more when the HQVDP driver is bound.
This solves the dependency we had on the file system availability.
The first time the HQVDP plane is used, we are sure that file system is
available so request_firmware function will match.
CONFIG_FW_LOADER_USER_HELPER_FALLBACK is then no more mandatory.

There's no use building the individual drivers as separate modules
because they are all only useful if combined into a single DRM/KMS
device.

Non-legacy drivers should only use this API to allow per-CRTC data to be
eventually moved into struct drm_crtc.

Better fit STI hardware structure.
Planes are no more responsible of updating mixer information such
as z-order and status. It is now up to the CRTC atomic flush to
do it. Plane actions (enable or disable) are performed atomically.
Disabling of a plane is synchronize with the vsync event.

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.
