ASoC: SOF: Intel: hda-sdw-bpt: use hda_dsp_dma_channel_pair_get/put

helpers

We use the host and link DMA SoundWire BTP. But hda_cl_prepare() doesn't
reserve the link DMA as code loader doesn't need. It works fine because
we assume the SwoundWire BPT will not run with audio streams
simultaneously. Change the helpers to hda_dsp_dma_channel_pair_get/put
to allow running BTP and audio stream simultaneously.
