[PATCH] powerpc: tidy-up of_register_driver()/driver_register() return values

Remove the assumption that driver_register() returns the number of devices
bound to the driver.  In fact, it returns zero for success or a negative
error value.

Nobody uses the return value of of_register_driver() anyway.
