Hi all!

Here's another revision of the ATI/AMD multichannel+HBR patchset.

- added customizable callbacks instead of polluting generic code
- fixed wrong codec id in rev3+ check (as previously noted)
- cosmetics

I've only tested this on NVIDIA/Intel, but I'd guess at least Peter
should be able to test this on AMD in a few days or so. The earlier
revisions were tested to fully work.

Combined patch can be found at: http://onse.fi/files/atihdmi5.patch
However, this patchset is on top recent sound-next commits so it does not
directly apply on older kernels.

Olivier, I hope you will be able to test this at some point as well
(same things as last time), even though it will be a bit more work :)
