[PATCH AUTOSEL 4.14 23/99] EDAC/mpc85xx: Prevent building as a module

[ Upstream commit 2b8358a951b1e2a534a54924cd8245e58a1c5fb8 ]

The mpc85xx EDAC driver 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

c92132f59806 ("edac/85xx: Add PCIe error interrupt edac support")

(Nov 2013).

[ bp: make it depend on EDAC=y so that the EDAC core doesn't get built
as a module. ]
