soundwire: intel_init: resume all devices on exit.

When the manager becomes pm_runtime active in the remove procedure,
peripherals will become attached, and do the initialization
process. We have to wait until all the devices are fully resumed
before the cleanup, otherwise there is a possible race condition where
asynchronous workqueues initiate transfers on the bus that cannot
complete. This will ensure there are no SoundWire registers accessed
after the bus is powered-down.
