ASoC: SOF: Intel: add hda_dma_prepare/cleanup helpers
SoundWire BPT stream needs to use link and host DMAs. Thus we need
helpers to prepare and cleanup the link and host DMAs. Currently the
SoundWire BPT stream uses hda_cl_prepare/cleanup helpers. It works fine
because we assume the SwoundWire BPT will not run with audio streams
simultaneously. The new helpers are copied from hda_cl_prepare/cleanup
and add a flag to reserve the paired host and link DMAs. The new helpers
will be used by both code loader and SoundWire BPT.
