The l12b and l15b supplies are used by components that are not (fully) described (and some never will be) and must never be disabled.
Out of curiosity, what are these components?
A host of things, including pull-ups, level shifters, regulators for (partially) described devices, but also things like the speakers and wlan.
Mark the regulators as always-on to prevent them from being disabled, for example, when consumers probe defer or suspend.
Note that these supplies currently have no consumers described in mainline.
