[POWERPC] Add rtas_service_present() helper
To test for the existence of an RTAS function, we typically do: foo_token = rtas_token("foo"); if (foo_token == RTAS_UNKNOWN_SERVICE) return; Add a rtas_service_present method, which provides a more conventional boolean interface for testing the existence of an RTAS method.
