Change restricted cpuset dynamically

Currently framework put tasks into restricted cpuset group when display
is off. However, when unlocking screen, SystemUI still runs in
restricted cpuset group leading to jank and delayed UDFPS action. This
CL mitigates problem by dynamically changing restricted cpuset group to
all cpus when display is back on.
