The newly added sti driver requires the drm_panel helpers,
and we get a link error if they are not enabled

ERROR: "drm_panel_attach" [drivers/gpu/drm/sti/stidvo.ko] undefined!
ERROR: "of_drm_find_panel" [drivers/gpu/drm/sti/stidvo.ko] undefined!

This adds a 'select' statement as we have for the other drivers.

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.

Add missing dependency on RESET_CONTROLLER in order to fix
the following build error.

drivers/gpu/drm/sti/sti_hdmi.c: In function 'sti_hdmi_probe'
drivers/gpu/drm/sti/sti_hdmi.c:780:2: error: implicit declaration of function 'devm_reset_control_get'
[-Werror=implicit-function-declaration]

Benjamin Gaignard remark:
I have change "depends on" to "select" but keep the original author name.

Make the link between all the hardware drivers and DRM/KMS interface.
Create the driver itself and make it register all the sub-components.
Use GEM CMA helpers for buffer allocation.

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.

Video Time Generator drivers are used to synchronize the compositor
and tvout hardware IPs by providing line count, sample count,
synchronization signals (HSYNC, VSYNC) and top and bottom fields
indication.
VTG are used by pair for each data path (main or auxiliary)
one for master and one for slave.
