drm/i915/lvds: Use struct intel_pps_delays for LVDS power sequencing

Reuse struct intel_pps_delays for the LVDS power
sequencing delays instead of hand rolling it all.
Perhaps in the future we could reuse some of the
same PPS code for both LVDS and eDP (assuming we
can decouple the PPS code from intel_dp...).
