Update the ALSA audio driver with upstream code (6.19 tree) to enable or improve support for new chipsets and audio codecs (mostly integrated on current motherboards and in notebooks).

This backport resolves (or should resolve) most of hardware enablement requests. The full patch set description will follow.

The changes in the ALSA code are tested with end users (we do not commit untested code). Because it is not possible to do tests on all affected hardware, I recommend to do tests on available hardware in our labs. I do not expect to have regressions. If there are some, I will try to fix them ASAP.
