[ALSA] snd-aoa: add snd-aoa
This large patch adds all of snd-aoa.
Consisting of many modules, it currently replaces snd-powermac
for all layout-id based machines and handles many more (for
example new powerbooks and powermacs with digital output that
previously couldn't be used at all).
It also has support for all layout-IDs that Apple has (judging
from their Info.plist file) but not all are tested.
The driver currently has 2 known regressions over snd-powermac:
* it doesn't handle powermac 7,2 and 7,3
* it doesn't have a DRC control on snapper-based machines
I will fix those during the 2.6.18 development cycle.
