ALSA: hda - Move azx_interrupt to hda_controller
This code will be reused by an hda_platform driver as it has no PCI dependencies. This allows update_rirb to be static as all users are now in hda_controller.c. Signed-off-by: Dylan Reid <dgreid@chromium.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
