Replace DEVICE_NOOP with noop_(set|read)_resources

`.read_resources` and `.set_resources` are the only two device
operations that are considered mandatory. Other function pointers
can be left NULL. Having dedicated no-op implementations for the
two mandatory fields should stop the leaking of no-op pointers to
other fields.
