[PATCH V3 5/5] Edac/85xx: Register mpc85xx_pci_err_driver by fsl_pci_driver

From: Chunhe Lan <Chunhe.Lan at freescale.com>

Now we registered pci controllers as platform devices. It will make edac
driver failed to register pci nodes as platform devices too. So we combine
two initialization code as one platform driver.
