The function drm_dsc_pps_infoframe_pack only packed the payload portion of the infoframe. Change the input struct to the PPS payload to clarify the function's purpose and allow for drivers with their own handling of sdp. (e.g. drivers with their own struct for all SDP transactions)

Again, ideally we'd want an AB from i915 guys as well.
