[PATCH] microblaze/pci: Fix compile error

[Hiroo Matsumoto <matsumoto.hiroo@xxxxxxxxxxxxxx>]

Hi


There is a compile error for microblaze pci because io_offset is not
declared. This patch adds declaration of io_offset.


* Compile error message
arch/microblaze/pci/pci-common.c: In function 'pcibios_setup_phb_resources':
arch/microblaze/pci/pci-common.c:1525: error: 'io_offset' undeclared
(first use in this function)
arch/microblaze/pci/pci-common.c:1525: error: (Each undeclared
identifier is reported only once
arch/microblaze/pci/pci-common.c:1525: error: for each function it
appears in.)
make[1]: *** [arch/microblaze/pci/pci-common.o] Error 1
make: *** [arch/microblaze/pci] Error 2


Regards.
