I think this is the issue Christoph Fritz reported earlier, DSS is being
initialized before TWL, and thus DSS doesn't find the regulators.

The proper fix is of course to make DSS support EPROBE_DEFER, but that's
easier said than done. I'll have a look if I can get it working enough
to fix this issue.
