fbcon: queue work on power efficient wqmaster-wq-migration-v5
fbcon uses workqueues and it has 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.
