Subject: [PATCH] EDAC, mpc85xx: Prevent building as a module

The mpc85xx EDAC code can be configured as a module but then fails to
build because it uses two unexported symbols:

  ERROR: ".pci_find_hose_for_OF_device" [drivers/edac/mpc85xx_edac_mod.ko] undefined!
  ERROR: ".early_find_capability" [drivers/edac/mpc85xx_edac_mod.ko] undefined!

We don't want to export those symbols just for this driver, so make
the driver only configurable as a built-in.

This seems to have been broken since at least commit c92132f59806
("edac/85xx: Add PCIe error interrupt edac support") (Nov 2013).
