[PATCH v4 12/12] drm/i915/dsc: make use of several params from drm_dsc_config

The code was ignoring (up to some point for rc_model_size) the
rc_model_size, rc_tgt_offset_high, rc_tgt_offset_low and rc_edge_factor
parameters from struct drm_dsc_config. Actually use them instead of
resorting to predefined constants.
