arch/microblaze also contains a declaration and implementation of
early_find_capability(), but as far as I can see, this was just copied
from powerpc, and it is never used on microblaze. So just as a matter
of good code hygiene, please add a patch to remove it from microblaze.
mpc85xx looks like a weird mix of platform driver and PCI device
driver. If loaded as a module, it shouldn't need
early_find_capability(); regular pci_find_capability() (or just
pci_is_pcie()) should work fine by the time we can load modules.
Maybe it would even work by the time mpc85xx_pci_err_probe() runs when
built-in.
The whole early_find_capability() thing seems a little questionable,
too, but it's really only used in the FSL enumeration path, so maybe
there's something really special about that system.
