soundwire: intel: move bus common sequences to different file
Now that the bus start/stop/clock_stop sequences use the ops, we can
move them to a different file to reuse them.
Note that we could in theory remove the abstraction for all those
sequences and directly call the functions in intel_auxdevice.c. To
allow for more flexibility and have means to special-case new
platforms, we decided to keep the abstraction. If in time it becomes
clear there is no benefit the abstraction will be simplified.
