[PATCH 07/14] drm/i915/dp: Move force_dsc_fractional_bpp_en check to intel_dp_dsc_valid_bpp()

[Jani Nikula]

Add the fractional DSC BPP force check to intel_dp_dsc_valid_bpp(), and
use that in xelpd_dsc_compute_link_config(). This is another step closer
towards unifying the platform specific functions.
