After encoder->pre_enable() hook, after link training sequence is
completed, PPS registers for DSC encoder are configured using the
DSC state parameters in intel_crtc_state as part of DSC enabling
routine in the source. DSC enabling routine is called after
encoder->pre_enable() before enbaling the pipe and after
compression is enabled on the sink.
v3:
* Configure Pic_width/2 for each VDSC engine when two VDSC engines per pipe
are used (Manasi)
* Add DSC slice_row_per_frame in PPS16 (Manasi)
v2:
* Enable PG2 power well for VDSC on eDP
