Subject: [PATCH] edac: Don't call mpc85xx_pci_err_probe() from fsl_pci_probe()

Don't call mpc85xx_pci_err_probe() from fsl_pci_probe() but instantiate the
PCI EDAC driver via the OpenFirmware interface.

Signed-off-by: Johannes Thumshirn <jthumshirn@...e.de>

Patch is untested due to lack of hardware and against Boris' for-next branch,
please test.
Thanks,
	Johannes
