So move the version info report to before the load attempt rather than only after a successful load. If the GuC does fail to load, then make the error messages visible rather than being 'debug' prints that do not appears in dmesg output by default. When waiting for the GuC to load, it used to be necessary to check for two different states - READY and (LAPIC_DONE | MIA_CORE). Apparently the second signified init complete on RC6 exit. However, in more recent GuC versions the RC6 exit sequence now finishes with status READY as well. So the test can be simplified. Also, add an enum giving all the current status codes that GuC loading can report as a reference without having to pull and search through the GuC source files.
