[PATCH v5 05/11] powerpc/eeh: Don't use driver member of struct pci_dev and further cleanups

["Uwe Kleine-König" <u.kleine-koenig@pengutronix.de>]

The driver member of struct pci_dev is to be removed as it tracks
information already present by tracking of the driver core. So replace
pdev->driver->name by dev_driver_string() for the corresponding struct
device.

Also move the function nearer to its only user and instead of the ?:
operator use a normal if which is more readable.
