Put the generic bits of the amp driver in sound/soc/codecs (there won't
be much).  At the minute you'll need to glue it in in via the machine
driver in the same way that OpenMoko does, there's not really any
support for multiple devices in the analouge part of the audio
subsystem.  This is on my radar to deal with, I have some systems where
it is relevant, but it's not there yet.
