From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
drm_calc_timestamping_constants() computes the pixel/line/frame
durations based on the crtc_ timing values. The corresponding pixel
clock is in mode->crtc_clock, so we need to use that instead of
mode->clock.
This should fix drm_calc_timestamping_constants() for frame packing
stereo modes.
