firmware: use power efficient workqueue for unloading and aborting fw load

Allow the scheduler to select the most appropriate CPU for running the
firmware load timeout routine and delayed routine for firmware unload.
This extends idle residency times and conserves power.

This functionality is enabled when CONFIG_WQ_POWER_EFFICIENT is selected.
