Subject: [PATCH] net: wireless: move regulatory timeout work to power
 efficient workqueue

For better use of CPU idle time, allow the scheduler to select the CPU
on which the timeout work of regulatory settings would be executed.
This extends CPU idle residency time and saves power.

This functionality is enabled when CONFIG_WQ_POWER_EFFICIENT is selected.
