[PATCH] powerpc/powernv: rename remaining rng powernv_ functions to pnv_

[PATCH] powerpc/powernv: rename remaining rng powernv_ functions to pnv_

[Jason A. Donenfeld]

The preferred nomenclature is pnv_, not powernv_, but rng.c used
powernv_ for some reason, which isn't consistent with the rest. A recent
commit added a few pnv_ functions to rng.c, making the file a bit of a
mishmash. This commit just replaces the rest of them.
