ASoC: SOF: Intel: hda-sdw-bpt: support simultaneous audio and BPT streams

Currently the SoundWire BPT stream uses the paired link DMA but not
reserve it. It works without any issue because we assume the SoundWire
BPT will not run with audio streams simultaneously.
To support simultaneous audio and BPT streams, we need to use the
hda_dma_prepare/cleanup helpers to reserve the pair link host DMA.
