Please make the entire comment a C++ one so things look more

So the top bits of the voltate selection field just get ignored? Might
be easier to just write the code to not include the top bits.

If the regulator doesn't have status readback it shouldn't provide a
get_status() operation.

Just don't provide the operation for these regulators then. That'll
mean a separate ops struct but that's fine.
