[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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
