fbcon: queue work on power efficient wqv3.10/topic/pe-wq
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.
