PCI: ftpci100: Rename macro name collision 

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.

../drivers/pci/controller/pci-ftpci100.c:37: warning: "PCI_IOSIZE" redefined
   37 | #define PCI_IOSIZE 0x00
