Turns out future DSI specific parameters aren't workable with the approach of having the encoder specific functions in intel_vdsc.c. Make intel_dsc_compute_params() a helper that does the encoder independent parts, and have encoder code call it. Move intel_dsc_dp_compute_params() to intel_dp.c as intel_dp_dsc_compute_params(). No functional changes. v2: Rename pipe_config to crtc_state while at it.
