Add aplaudio(4) and aplmca(4).  The aplmca(4) driver controls the hardware
block that takes data from apldma(4), serializes it and sends it out on
the i2s ports.  The aplaudio(4) driver ties together aplmca(4) and various
codecs to present an audio(4) interface to the system.

This is still WIP, but good enough to play back audio on the speaker in the
M1 mini.
