ALSA: hda - Raise AZX_DCAPS_RIRB_DELAY handling into top drivers
AZX_DCAPS_RIRB_DELAY is dedicated only for Nvidia and its purpose is just to set a flag in bus. So it's better to be set in the toplevel driver, either hda_intel.c or hda_tegra.c, instead of the common hda_controller.c. This also allows us to strip this flag from dcaps, so save one more bit there. Signed-off-by: Takashi Iwai <tiwai@suse.de>
