ASoC: SOF: Intel: hda-mlink: add helper to program SoundWire PCMSyCM registers
These registers enable the HDaudio DMA hardware to split/merge data
from different PDIs, possibly on different links.
This capability exists for all types of HDaudio extended links, but
for now is only required for SoundWire. In the SSP/DMIC case, the IP
is programmed by the DSP firmware.
