[PATCH 22/24] drm/vblank: pass vblank to drm_vblank_disable_and_save(), make static

[Jani Nikula <jani.nikula@intel.com>]

Use the vblank pointer instead of a dev, pipe pair to simplify code.

drm_vblank_disable_and_save() is also no longer used outside of
drm_vblank.c; make it static while at it.
