[PATCH 29/33] qemu: add 'modelName' value for pnv-phb4-root-port device

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

Use the 'modelName' attribute for the pnv-phb4-root-port device.

Let's also take this opportunity to adapt the
virDomainControllerIsPowerNVRootPort() helper to also recognize
pnv-phb4-root-port as a PowerNV root port. This will spare us from
duplicating checks where the constraints of pnv-phb3-root-port also
applies for the pnv-phb4-root-port device.
