hw/ppc/spapr_rng: Introduce CONFIG_SPAPR_RNG switch for spapr_rng.c
The spapr-rng device is suboptimal when compared to virtio-rng, so
users might want to disable it in their builds. Thus let's introduce
a proper CONFIG switch to allow us to compile QEMU without this device.
The function spapr_rng_populate_dt is required for linking, so move it
to a different location.
