regulator: rpm-smd-regulator: Add support for proxy consumers 



Add support to enforce proxy consumer requests defined in device
tree for rpm-smd-regulator devices.  These can be used to ensure
that regulators are not accidentally disabled or scaled down
before all consumers have had a chance to make their own requests.
