The HW docs aren't very detailed on this point, but they certainly don't
state that these bits control a regulator (or power domain as mentioned
later in the thread). I guess it's possible, but it feels like an
assumption to me. The HW modules seem small enough that it doesn't feel
likely anyone would have bothered with power-gating them.
