[PATCH v2 27/29] conf, qemu: add 'pnv-phb4' controller model name

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

Similar to the existing pnv-phb3 device, pnv-phb4 is also an
implementation of pcie-root. No user doc is needed in this case since
the user doesn't ideally set PCI model names manually.
