soundwire: intel: start using hw_ops
Before introducing new hardware with completely different register
spaces and programming sequences, we need to abstract some of the
existing routines in hw_ops that will be platform-specific. For now we
only use the 'cnl' ops - after the first Intel platform with SoundWire
capabilities.
Rather than one big intrusive patch, hw_ops are introduced in this
patch so show the dependencies between drivers. Follow-up patches will
introduce callbacks for debugfs, power and bus management.
