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.

Purpose is to simplify the STI driver:
- remove layer structure
- consider video subdev as part of the compositor (like mixer subdev)
- remove useless STI_VID0 and STI_VID1 enum

For stih407 SoC enable the second mixer to get two CRTC.
Allow GPD planes and encoders to be connected to this new CRTC.
Cursor plane can only be set on first CRTC.
GPD clocks needed change the parent clock depending on which
CRTC GPD are used.

Compositor control all the input sub-device (VID, GDP)
and the mixer(s).
It is the main entry point for composition.
Layer interface is used to control the abstracted layers.
Add debug in mixer and GDP.

Generic Display Pipeline are one of the compositor input sub-devices.
GDP are dedicated to graphic input like RGB plans.
GDP is part of Compositor hardware block which will be introduce later.
A sti_layer structure is used to abstract GDP calls from Compositor.
