soundwire: intel: disable WAKEEN in pm_runtime resume

When the manager device is pm_runtime resumed, we see a series of
spurious wakes and attempts to resume the same device:

soundwire_intel.link.0: intel_resume_runtime: start
soundwire_intel.link.0: intel_link_power_up: powering up all links
soundwire_intel.link.0: intel_link_power_up: first link up, programming SYNCPRD
soundwire_intel.link.0: intel_shim_wake: WAKEEN disabled for link 0
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume start
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume done
soundwire_intel.link.0: intel_shim_wake: WAKEEN disabled for link 0
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume start
soundwire_intel.link.0: intel_link_process_wakeen_event: pm_request_resume done

This sequence does not break anything but is totally unnecessary.

Currently the wakes are only disabled after the peripheral generates a
wake, e.g. for jack detection.

If the resume is initiated by the host drivers as a result of
userspace actions (play/record typically), we need to disable wake
detection as well. Doing so prevents the spurious wakes and calls to
pm_request_resume().
