microblaze: switch to GENERIC_PCI_IOMAP
microblaze copied pci_iomap from generic code, probably to avoid
pulling the rest of iomap.c in. Since that's in
a separate file now, we can reuse the common implementation.
The only difference is handling of nocache flag,
that turns out to be done correctly by the
generic code since arch/microblaze/include/asm/io.h
defines ioremap_nocache same as ioremap.
