When getting translated from a downstream device tree that used slightly different DT bindings, these regulators got labeled with the "on-in-suspend" state, when they were actually supposed to be turned off for S3 suspend. This was harmless, but not intentional, AFAICT. Let's turn them off to get the optimal power state.
