drm/i915/dp: Set the DSC link limits in intel_dp_compute_config_link_bpp_limits

drm/i915/dp: Set the DSC link limits in intel_dp_compute_config_link_bpp_limits

The helper intel_dp_compute_config_link_bpp_limits is the correct place
to set the DSC link limits. Move the code to this function and remove
the #TODO item.

v2: Add argument intel_connector to the helper to get correct connector
for DP MST. (Imre)

v3: Remove redundant calls to intel_dp_dsc_sink_max_compressed_bpp as
its already accounted while setting link bpp limits.
