Staging: sst: Intel SST audio driver

This is the Intel SST audio driver.

As compared to the previous versions it has all the printks and other stuff
noted cleaned up and more hardware support. The Aava support is disabled in
this patch (is_aava resolves to 0) because the Aava board detection logic
is not yet upstream.

The driver itself is a combination of a traditional ALSA driver and a
hardware assisted offload driver which can play audio while the processor
is asleep but which can't do all the more interactive stuff.

In the general case most software would use the ALSA interface, but the
other interface is needed for certain classes of use such as music playback
on highly power consumption sensitive devices.

This is going to staging primarily because it depends upon the staging memrar
driver.
