powerpc/cpuidle: cpuidle driver for pSeries
This patch implements a back-end cpuidle driver for pSeries based on pseries_dedicated_idle_loop and pseries_shared_idle_loop routines. The driver is built only if CONFIG_CPU_IDLE is set. This cpuidle driver uses global registration of idle states and not per-cpu.
