[PATCH v8 5/7] POWER/cpuidle: Generic POWERPC-BOOK3S CPUIDLE driversupporting PSERIES.

[Deepthi Dharwar]

This patch includes cleanup and refactoring of the
existing code to make the driver POWERPC-BOOK3S generic.
* Re-naming the functions from pseries to generic powerpc-book3s.
* Re-naming the backend driver from pseries_idle to
  powerpc_book3s_idle.
