[ALSA] hda-codec - Support for SigmaTel 9872

- Added commentary about STAC9225s which shares the same id as CXD9872RD.
- Added entry for 7662 but won't work automatically until pci_subdevice

- 'vaio' model now corresponds to CXD9872RD_VAIO for backward compat.

Simple patch to enable Message Signalled Interrupts for the HDA Intel
audio controller. Tested with:
Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)
MSI is better because it means audio doesn't end up sharing IRQ with USB.
