hda: add hda-micro codec

It's identical to the hda-duplex codec, except that it advertises the
input as microphone instead of line-in and the output as speaker instead
of line-out.  Some guest apps (microsoft netmeeting being one) are picky
when it comes to selecting the recording source and don't accept
line-in, so give them what they expect.
