Since the sharpness filter is now fully integrateds into the normal pfit code intel_pfit_compute_config() must be called from the encoder .compute_config() on all relevant output types. Sharpness filter is supported on LNL+ so only HDMI and DP SST/MST outputs are actually relevant. I already took care of HDMI and DP SST, but (as usual) forgot about DP MST. Add the missing intel_pfit_compute_config() call to make the sharpness filter operational on DP MST as well.
