[PATCH v3 24/29] qemu: introduce QEMU_CAPS_DEVICE_PNV_PHB4

[Daniel Henrique Barboza]

This capability enables two devices:

- pnv-phb4 device, the pcie-root controller for PowerNV9 domains
- pnv-phb4-root-port, the pcie-root-port model that is used with the
pnv-phb4 device.

As with the pnv-phb3 devices, these are also user creatable only after
QEMU 6.2.0 but the capability is available since 5.0.0, meaning that we
need to check QEMU version and arch manually before setting it.
