drm: Use crtc_clock in drm_calc_timestamping_constants()
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.
