[src/trunk]: src/sys/arch/macppc/dev add basic support for iMac G5 audio:



details:   https://anonhg.NetBSD.org/src/rev/0300d224775b
branches:  trunk
changeset: 1019478:0300d224775b
user:      macallan <macallan%NetBSD.org@localhost>

description:
add basic support for iMac G5 audio:
- match AOAShasta
- deal with headphone gpios labeled as lineout in OF
- set sc_mode to SNAPPER_IS_PCM3052 - OF makes it look like an unlabeled
  TAS3004
TODO:
- actually support pcm3052 instead of treating it like a sw codec
