superio/ite: Add special fan vectors

A number of ITE SIOs support "special fan control vectors", which
effectively allow non-linear fan speed control. This is for example used
by the vendor firmware of the "HP Pro 3500 Series".

The special vector registers won't be written to until the mb's
devicetree configures `FAN_VECX.tmp_start != 0`.
