[SERIAL] Expose 8250_pci setup/removal/suspend/resume functions
Re-jig the setup/removal/suspend/resume of 8250 pci ports so that they
know slightly less about how they're attached to a PCI device. Expose
this as the new interface for registering PCI serial ports, as well as
the pciserial_board structure and associated flag definitions.
