It should also support unconditionally registering devices, if it no
longer does so that's a regression in the framework which should be
fixed.  Looking at mfd_add_devices() I can't see an issue though, both
ACPI and DT information is optional - the entire DT section in
mfd_add_device() will be skipped if no of_compatible is specified in the
cell.  Are you *sure* that the regulator driver isn't running?
