Subject: ALSA: hda - Add standard channel maps

Although HD-audio allows pair-wise channel configurations, only the
fixed channel positions are used in this version.  In future, this can
be changed and allow user to modify the channel positions.

Subject: ALSA: hda - Provide the proper channel mapping for generic HDMI
 driver

... instead of the standard fixed channel maps.
The generic HDMI is based on the audio infoframe, and its configuration
can be selected via CA bits.  Thus we need a translation between the
CA index and the verbose channel map list.

Subject: ALSA: hda - Fix channel maps for Nvidia 7x 8ch HDMI codecs

Some old Nvidia HDMI codecs with 8ch support only 2/8 or
2/6/8 channels and with the fixed CLFE-first map.

Subject: ALSA: ac97: Implement channel map workaround for ALC650

ALC650 has a channel swap option between surround and CLFE channels,
so we need to tweak the channel maps dynamically depending on the
register bit.

Now struct snd_ac97 can contain chmap pointers for playback and
capture.  The driver may store these and let ac97 driver changing the
channel mapping dynamically.

Subject: ALSA: Define more channel map positions

For following the standard, define more channel map positions and
shuffle the items a bit:

- As both PulseAudio and gstreamer define MONO channel position
  explicitly, we should follow that, too.  The mono streams point to
  this channel position unless they are explicitly assigned to certain
  channel positions.

- Top-front-* and Top-rear-* positions are added, carried from
  PulseAudio's definitions.

- Move NA and MONO definitions at the top of table right after
  UNKNOWN, since these are more abstract in comparison with other
  practical positions.
