[ALSA] hda-codec - Support for SigmaTel 9872

- AR11M and AR11S uses the same chip hence we claim to support the AR Series.
- Added commentary about STAC9225s which shares the same id as CXD9872RD.
- Added entry for 7662 but won't work automatically until pci_subdevice
  is known.
- 'vaio' model now corresponds to CXD9872RD_VAIO for backward compat.
- Replaced STAC766x_VAIO with CXD9872RD_VAIO, STAC9872AK_VAIO, STAC9872K_VAIO
  and CXD9872AKD_VAIO
- Added 'vaio-ar' model for potential future modifications.
