powerpc: Add includes to fix powernv/rng.c build

Caused by commit a4da0d50b2 ("powerpc: Implement
arch_get_random_long/int() for powernv") from the powerpc tree
interacting with commit b5b4bb3f6a ("of: only include prom.h on sparc")
from the dt-rh tree.

I added this merge fix patch (which will need to be sent to Linus when
these two trees get merged, or could be applied now to the powerpc tree):

[ Also add linux/smp.h to get cpu_to_chip_id -- BenH ]
