A basic OMAP AVS driver has been in mainline for a long time, yet we
have not seen support submitted for all of these features.

When folks are motivated to propose such changes upstream, we will be
happy to discuss them and add support for them to the AVS driver.

Until then, the primary purpose of this series is to do some minimal
cleanup of an *existing* driver so it can be moved into drivers/*. New
features can be added there as easily as they could've been added when
it was a driver under arch/arm.
