ALSA: doc: ReSTize HD-Audio document The original HD-Audio.txt was already in asciidoc format, so it's a simple conversion in the end. A new subdirectory, Documentation/sound/hd-audio, is created and the document is moved there with another file name to match better with the recent Documentation tree structure.

ALSA: doc: Document PC Beep Hidden Register on Realtek ALC256 This codec (among others) has a hidden set of audio routes, apparently designed to allow PC Beep output without a mixer widget on the output path, which are controlled by an undocumented Realtek vendor register. The default configuration of these routes means that certain inputs aren't accessible, necessitating driver control of the register. However, Realtek has provided no documentation of the register, instead opting to fix issues by providing magic numbers, most of which have been at least somewhat erroneous. These magic numbers then get copied by others into model-specific fixups, leading to a fragmented and buggy set of configurations. To get out of this situation, I've reverse engineered the register by flipping bits and observing how the codec's behavior changes. This commit documents my findings. It does not change any code.
