Pi3 vchiq driver?

[Karl Denninger]

I assume this will provide the audio service (which is currently not
available) on the Pi3.

Attempting to include it results in a handful of compilation errors. 
They'd be easy to fix for the instant case but generalizing them so they
ALSO compile on the Pi2 would likely be a good idea, and I'm
less-certain on the "right" way to do that.

The errors are generally of the form (once I fixed a missing include in
atomic.h):
