PCI/portdrv: Remove pcie_port_bus_type link order dependency
The pcie_port_bus_type must be registered before drivers that depend on it
can be registered. Those drivers include:
pcied_init() # PCIe native hotplug driver
aer_service_init() # AER driver
dpc_service_init() # DPC driver
pcie_pme_service_init() # PME driver
Previously we registered pcie_port_bus_type from pcie_portdrv_init(), a
device_initcall. The callers of pcie_port_service_register() (above) are
also device_initcalls. This is fragile because the device_initcall
ordering depends on link order, which is not explicit.
Register pcie_port_bus_type from pci_driver_init() along with pci_bus_type.
This removes the link order dependency between portdrv and the pciehp, AER,
DPC, and PCIe PME drivers.
