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.

TODO

----



Get the memrar driver cleaned up and upstream (dependancy blocking SST)

Get the jack header entries accepted

Review the printks and kill off any left over ST_ERR: messages

Review the misc device ioctls for 32/64bit safety and sanity

Review the misc device ioctls for size safety depending on config and decide

	if space/unused areas should be left



Anything the sound folks turn up on full review
