drm: Add old state pointer to CRTC .enable() helper function
The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.
While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.
