pnv_phb4.c: make pnv-phb4-root-port user creatable
We want to create only the absolutely minimal amount of devices when running with -nodefaults. The root port is something that the machine can boot up without. But, to do that, we need to provide a way for the user to add them by hand. This patch makes pnv-phb4-root-port user creatable and then uses the pnv_phb_attach_root_port() helper to add a pnv_phb4_root_port only when running with default settings.
