ASoC: SOF: Intel: hda-mlink: add helpers for sync_arm/sync_go
The multi-link synchronization uses the same concept and registers,
but moved to the HDAudio extended links.
Add helpers for sync_arm and sync_go which are the basic for the bus
reset, bank switch and clock stop.
Since SoundWire is the only user of those helpers, only expose the
_unlocked versions for now.
Note that SYNCGO is a write-only bit, so no error can be reported. We
still return 0 for compatibility with the SoundWire stream management
headers.
