drm: Wrap the check for atomic_commit implementation
This check is useful for drivers that do not have DRIVER_ATOMIC set but
have atomic modesetting internally implemented. Wrap the check into a
function since this is used in many places and as a bonus, the function
name helps to document what the check is for.
v2:
Change return type to bool (Ville)
Move the function drm_atomic.h (Daniel)
