powerpc/ps3: make system bus's remove and shutdown callbacks return void
The driver core ignores the return value of struct device_driver::remove because there is only little that can be done. For the shutdown callback it's ps3_system_bus_shutdown() which ignores the return value. To simplify the quest to make struct device_driver::remove return void, let struct ps3_system_bus_driver::remove return void, too. All users already unconditionally return 0, this commit makes it obvious that returning an error code is a bad idea and ensures future users behave accordingly.
