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.
