iio: pressure-core: st: Provide support for the Vdd_IO power supply
The power to some of the sensors are controlled by regulators. In most cases these are 'always on', but if not they will fail to work until the regulator is enabled using the relevant APIs. This patch allows for the Vdd_IO power supply to be specified by either platform data or Device Tree.
