drm/i915: Add audio sync_audio_rate callback
Add the sync_audio_rate callback. With the callback, audio driver can trigger i915 driver to set the proper N/CTS or N/M based on different sample rates. Signed-off-by: Libin Yang <libin.yang@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
