[PATCH v3 25/29] conf, qemu: add 'pnv-phb4-root-port' PCI controller model name

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

This device is an implementation of pcie-root-port, similar to its
sibling pnv-phb3-root-port. Since it's a new model name that Libvirt
automatically sets, we refrain from documenting it to users.
