[PATCH] Add support for PowerMac3,5 in snd-aoa ALSA sound module

["Linux User #330250" <linuxuser330250@gmx.net>]

Hello!

About two years ago Johannes Berg wrote support for the PowerMac3,6 aka G4 =
MDD=20
which I was using as a desktop computer then. Johannes wrote all the code, =
and=20
I tested it.

I now have a PowerMac3,5 =E2=80=93 yes, an earlier model.

This patch makes the snd-aoa ALSA sound module support the TAS3001C codec o=
f=20
my Apple Power Mac G4 "Quicksilver" (2001 model). I suppose it will also wo=
rk=20
for the "Quicksilver 2002", since both identify as PowerMac3,5.

The patch also changes a few comments to name the exact Power Mac model mor=
e=20
accurately in sound/aoa/fabrics/layout.c.

This is my first contribution to the linux kernel ever, so I hope you will =
be=20
kind to me. I am not a programmer, but adding already supported devices was=
 a=20
task even I could accomplish.

Thanks,
Andreas  aka  Linux User #330250
