KVM: PPC: Use arch_get_random_seed_long instead of powernv variant
The powernv_get_random_long() does not work in nested KVM (which is
pseries) and produces a crash when accessing in_be64(rng->regs) in
powernv_get_random_long().
This replaces powernv_get_random_long with the ppc_md machine hook
wrapper.
