This is fairly obviously broken - it's overwriting the normal runtime
value, this will disrupt the running system if we want the value we use
on suspend is different to the value we want at runtime.

Think about it - if this was a sane thing to do the core would just do
it without needing driver specific code, we already know how to set the
voltage for the device.
