A couple of things here:
- Fixes for pbias that didn't make it in during the merge window due to
the driver coming in via MMC. The conversion to use helpers is a
fix as it implements list_voltage() which the main user (MMC) relies
on for correct functioning.
- Change the !REGULATOR stub for optional regulators to return an
error rather than a dummy; this is more in keeping with the intended
use of optional regulators and fixes some issues seen MMC where it
got confused by a dummy being provided.
