powerpc: Simplify pSeries idle loop
Since pSeries only wants to do something different in the idle loop when
there is no work to do, we can simplify the code by implementing
ppc_md.power_save functions instead of complete idle loops. There are
two versions: one for shared-processor partitions and one for dedicated-
processor partitions.
With this we also do a cede_processor() call on dedicated processor
partitions if the poll_pending() call indicates that the hypervisor
has work it wants to do.
