Revert "sb/intel/common/acpi: Add more Windows versions"
This reverts commit cc805d9dd64ca2d3c8de2b2de2ea7c53b387ff8f. Advertising certain Windows versions triggers different paths in the OS. As there may also be device specific quirks in the OS, such changes need to be tested thoroughly on all affected devices. There was at least one very subtle regression introduced by this. When Linux sees "Windows 2012" support advertised, it disables the `acpi_video` backlight controls, at least on devices with Intel IGD. Without user-space handling the ACPI events, keyboard backlight controls stop working. Moreover, the commit message didn't state any reason for this change. Why was it merged?
