t480/3050micro: disable hyperthreading 

Hyperthreading is a risk factor for spectre/meltdown
and other attacks.

Disabling it is a best practise. Those who need it
can always turn this option back on. Otherwise, disabling
it by default is a simply courtesy to the average user,
in the interest of security.
