pnv_init() creates "power10_v1.0-pnv-chip", "power8_v2.0-pnv-chip",
"power8e_v2.1-pnv-chip", "power8nvl_v1.0-pnv-chip", or
"power9_v2.0-pnv-chip" sysbus devices in a way that leaves them
unplugged.

pnv_chip_power9_instance_init() creates a "pnv-xive" sysbus device in
a way that leaves it unplugged.

Create them the common way that puts them into the main system bus.
Affects machines powernv8, powernv9, and powernv10.  Visible in "info
qtree".  Here's the change for powernv9:
