From: Ville Syrjälä ville.syrjala@linux.intel.com
Pull the "do we want to enable audio?" computation into a small helper to make intel_hdmi_compute_config() less messy. Will make it easier to add more checks for this later (eg. we should actually be checking at the hblank is long enough for audio transmission).
