drm/i915/mst: Call intel_pfit_compute_config() for sharpness filter

The sharpness filter property is on the CRTC (as opposed to the
connector) so the expectation is that it's usable on all output
types. 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.
