If read byte fails, use read byte data for detecting ENE controller

* The Nuvoton NCT6793D Super-IO SMBus controller does not actually support read byte or quick operations.  The driver used for Windows and in the OpenRGB kernel patch will perform a read byte data operation in its place with a dummy address, but the driver I'm submitting upstream is not going to have this hack.  All controllers that could be used on a Nuvoton SMBus will need a detection path that doesn't rely only on byte read or quick operations.
