iio: adc: ad7606: add enabling of optional Vrefin voltage

Browse source

Add optional refin voltage enabling. The property "refin-supply" is
already available and optional in the current fdt dt_schema.

Note that the driver does not need to take any actions if the supply
is not present because a pin strap is used to change the behavior
of the device if an external reference is connected.
