PCI_IOSIZE is defined in mach-loongson64/spaces.h, so change the name
of the PCI_* macros in pci-ftpci100.c to use FTPCI_* so that they are
more localized and won't conflict with other drivers or arches.

v2: prefix PCI_ macro names with "FT", thus use FTPCI_ for these macro names.
    (suggested by Linus Walleij)
