In the spec (which is not publically available, sorry), this
0x00120075 device is described as "Throttle thermal policy" which
takes values 0 for default, 1 for overboost, 2 for silent.

I don't know exactly how this differs from "fan boost" but I suggest
mirroring the spec here, offer this as a separate sysfs control named
according to the spec, separate it from fan boost mode.

Thanks,
Daniel
