powerpc: enable to run posix cpu timers in task context

Browse Source 
Now that all kvm entry to guest paths handle the task work
using the generic framework, enable HAVE_POSIX_CPU_TIMERS_TASK_WORK
which allows running posix cpu timers in task context instead of running
them in hardirq. This would is a necessary step towards enabling
PREEMPT_RT on powerNV systems.
