hw/nx: Fix NX BAR assignments
The NX rng BAR is used by each core to source random numbers for the
DARN instruction. Currently we configure each core to use the NX rng of
the chip that it exists on. Unfortunately, the NX can be deconfigured by
hostboot and in this case we need to use the NX of a different chip.
This patch moves the BAR assignments for the NX into the normal nx-rng
init path. This lets us check if the normal (chip local) NX is active
when configuring which NX a core should use so that we can fallback
gracefully.
