[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.
