mb/clevo/cml-u: Fix CMOS options

The `hyper_threading` CMOS option was hooked up to the wrong enumeration
and lacked a default value in `cmos.default`. Thus, use the correct enum
for the `hyper_threading` option, remove the now-unused "backwards" enum
and provide a default value in `cmos.default`.
