An unsafe but universal implementation for the ACPI Embedded Controller IO interface for Windows

It is unsafe because of possible race condition between this application and the PC firmware when writing to the EC registers. For a safe approach ACPI/WMI methods have to be used, but those are different for each motherboard model.

This is a controller present on some Gigabyte motherboards for both Intel and AMD, that is in custom firmware loaded onto the 2nd ITE EC. It can be accessed by using memory mapped IO, mapping its internal RAM onto main RAM via the ISA Bridge. This class can disable it so that the regular IT87XX code can drive the fans.
