ALSA: hda - Use common codes for ATI, Nvidia and VIA simple codecs
The code refactoring using the same helper functions for sharing the codes among ATI, Nvidia and VIA simple_hdmi* stuff. Except for that spec->pcm_playback is no longer pointer, the functionality doesn't change. Signed-off-by: Takashi Iwai <tiwai@suse.de>
