Subject: [PATCH] arch/microblaze/pci/pci-common.c: Export 'isa_io_base' for
 compiling break

Export it just like another architectures have done (e.g. powerpc). The
related error with allmodconfig:

  ERROR: "isa_io_base" [sound/pci/vx222/snd-vx222.ko] undefined!
  ERROR: "isa_io_base" [sound/pci/trident/snd-trident.ko] undefined!
  ...
  ERROR: "isa_io_base" [drivers/ata/pata_artop.ko] undefined!
  ERROR: "isa_io_base" [drivers/ata/libata.ko] undefined!
  make[1]: *** [__modpost] Error 1
  make: *** [modules] Error 2
