From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Update TRANS_SET_CONTEXT_LATENCY in intel_set_transcoder_timings_lrr()
as well. While for actual LRR updates this should not change, I want
to reuse this code to also sanitize the vblank delay during boot,
and in that case we do need to update this.
