powerpc/cpuidle: Enable cpuidle and directly call cpuidle_idle_call() for pSeries
This patch enables cpuidle for pSeries and pSeries_idle is directly called from the idle loop. As a result of pSeries_idle, cpuidle driver registered with cpuidle subsystem comes into action. On failure of loading of the driver or cpuidle framework default idle is executed as part of the function. This patch also removes the routines pseries_shared_idle_sleep and pseries_dedicated_idle_sleep as they are now implemented as part of pseries_idle cpuidle driver.
