We have two very similar root-port devices, pnv-phb3-root-port and pnv-phb4-root-port. Both consist of a wrapper around the PCIESlot device that, until now, has no additional attributes. The main difference between the PHB3 and PHB4 root ports is that pnv-phb4-root-port has the pnv_phb4_root_port_reset() callback. All other differences can be merged in a single device without too much trouble. This patch introduces the unified pnv-phb-root-port that, in time, will be used as the default root port for the pnv-phb device.
