Currently we are including both max_requested_bpc and
limits->pipe.bpp_max while computing maximum possible pipe bpp with dsc.
However, while setting limits->pipe.max_bpp, the max_requested_bpc is
already taken into account.
Drop the redundant check for max_requested_bpc and use only
limits->pipe.bpp_max. This will also result in dropping conn_state
argument in functions where it was used only to get max_requested_bpc.
