[PATCH v3 7/9] powerpc/powernv: Add platform support for stop instruction

POWER ISA v3 defines a new idle processor core mechanism. In summary, a) new instruction named stop is added. This instruction replaces instructions like nap, sleep, rvwinkle. b) new per thread SPR named PSSCR is added which controls the behavior of stop instruction. PSSCR has
