drm/vblank: Document drm_crtc_vblank_restore constraints
I got real badly confused when trying to review a fix from Ville for
this. Let's try to document better what's required for this, and check
the minimal settings at runtime - we can't check ofc that there's
indeed no races in the driver callback.
Also noticed that the drm_vblank_restore version is unused, so lets
unexport that while at it.
