[PATCH] mxser_new: fix non-PCI build
When CONFIG_PCI is not defined (i.e. PCI bus is disabled), the mxser_new
driver fails to link, since some pci functions are not available. Fix this
behaviour to be able to compile this driver on machines with no PCI bus
(but with ISA bus support).

Say Y here if you have a Moxa SmartIO multiport serial card and/or
want to help develop a new version of this driver.
