The SAW2 device can optionally provide a voltage regulator supplying the
CPU core, cluster or L2 cache. Describe it in the device bindings.

There was such property in the binding (and DTS!) but a bool. Previous
patch silently dropped it, so re-introducing it with different type is
confusing.

Could you please propose a better name here? saw-regulator? Or maybe 
regulator-saw? (as we might get regulator-avs at some point).
