drm: Pass the display mode to drm_calc_timestamping_constants()
We don't really use hwmode anymore in i915, so eliminating its use from the core code seems prudent. Just pass the appropriate mode to drm_calc_timestamping_constants(). Reviewed-by: mario.kleiner.de@gmail.com Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>
