[PATCH 32/33] qemu: add 'modelName' value for pnv-phb4 device

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

Use the 'modelName' attribute for the pnv-phb4 pcie-root device. Update
the virDomainControllerIsPowerNVPHB() helper as well so this device
receives the same handling the existing pnv-phb3 has.
