drm/i915: Call drm_calc_timestamping_constants() earlier
Update the pixel/line/frame duration information when we switch to the new pipe config. This will keep the timestamping constants in better sync with the real hardware state. Reviewed-by: mario.kleiner.de@gmail.com Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com>
