For AMBA devices with unconfigured driver override, the "driver_override" sysfs virtual file is empty, while it contains "(null)" for platform and PCI devices.
Make AMBA consistent with other buses by dropping the test for a NULL pointer.
Note that contrary to popular belief, sprintf() handles NULL pointers fine; they are printed as "(null)".
