Phylib uses workqueues for multiple purposes. There is no real dependency of
scheduling these on the cpu which scheduled them.
On a idle system, it is observed that and idle cpu wakes up many times just to
service this work. It would be better if we can schedule it on a cpu which the
scheduler believes to be the most appropriate one.
This patch replaces system_wq with system_power_efficient_wq for PHYLIB.
