From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
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).
