drm/dp: Add drm_dp_dsc_sink_slice_count_mask()

Browse source

A DSC sink supporting DSC slice count N, not necessarily supports slice
counts less than N. Hence the driver should check the sink's support for
a particular slice count before using that slice count. Add the helper
functions required for this.
