stih416 chip family is no more supported in Linux v4.9.
It is then useless to keep sti_vtac.c file since it not used at all for
the stih407/10 chip family supported by sti driver.

Use drm_dev_alloc() and drm_dev_register() instead of .load()
To simplify init sequence only create fbdev when requested
in output_poll_changed().

version 2:
remove call to drm_connector_unregister_all() and
drm_dev_set_unique()

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.

v1: This patch does the minimum to make sti driver use atomic helpers.
No big bang, only adapt some functions to new call order.

v2: Use dpms and page flip atomic helpers

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.
