Fix the output ports on the AD1988 codec. From the submitter:

Affects to people WITH an AD1888 codec, the system will output to the port
labeled "speaker" instead of microphone.  System will work the same in
multiple operating systems.

If people are currently using their systems with this codec they will need
to swap their output ports.

I have _not_ checked audio input or line input (basically, I have checked
nothing other than line-out).

I believe this is an appropriate change, it makes us consistent with
documentation, and other operating systems.  Furthermore, this feature
(playing) is the vast majority of sound activities, so if this makes is
right for playback and wrong for recording... playback is more important,
and we can fix recoding in the future without worries of screwing people
again in the future (since we'll be "right" on the playback).
