[PATCH 3/3] drm/i915: Initialize drm_driver vblank funcs at compile time

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Move the .get_vblank_timestamp() and .get_scanout_position()
initialization to happen at compile time. No point in delaying
it since we always assign the same functions.
