powerpc/powernv: delay rng platform device creation until later in boot
The platform device for the rng must be created much later in boot.
Otherwise it tries to connect to a parent that doesn't yet exist,
resulting in this splat:
[ 0.000478] kobject: '(null)' ((____ptrval____)): is not initialized, yet kobject_get() is being called.

[ 0.003623] [c000000002a0fe20] [c000000002060c38] random_init+0xc0/0x214
This patch fixes the issue by doing the platform device creation inside
of machine_subsys_initcall.
