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

The pps timestamp initialization was accidentally lost on vlv/chv in

 commit a4a5d2f8a96e09844a91469e889f15bd5e927399

    drm/i915: Track which port is using which pipe's power sequencer

Restore it so that we avoid introducing random delays into the pps operations
during/after driver init time.
