ASoC: SOF: Intel: remove circular dependency for

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

The SoundWire BPT support will rely on the HDaudio DMA. This exposes a
circular dependency module dependency which has to be resolved by
splitting common parts used by HDaudio and SoundWire parts, and
'generic' parts used by HDaudio only.

This patchset does not change any functionality, it just moves code
around, exposes symbols that are used in the new module. The code has
been in use for more than one kernel cycle already so it really
shouldn't break any existing platforms.

The main issue with such code moves is that it makes backports or
fixes more complicated. That's the main reason why we held back these
patches until we were reasonably confident on the maturity of MTL and
LNL drivers.
