The l12b and l15b supplies are used by components that are not (fully)
described (and some never will be) and must never be disabled.

Mark the regulators as always-on to prevent them from being disabled,
for example, when consumers probe defer or suspend.

Note that there are likely votes from other processors for these rpmh
regulators (at least for l15b) but the OS should not rely on that in any
case.

Included is also a patch that adds the missing HID supplies for the
T14s. It was a corresponding change for the CRD that made me look into
this to make sure these supplies were not disabled during suspend or on
probe deferrals.
