For all drivers that make use of ssb_pcihost_probe() (i.e.
b43_pci_bridge_driver and b44_pci_driver) the driver name is set.
As at the time for the function is called __pci_register_driver() already
assigned drv->driver.name to hold the same value, use
dev_driver_string() with the same result.

This has the upside of not requiring the driver member of struct pci_dev
which is about to be removed and being simpler.

Makes sense.
