hwmon: qpnp-voltage: Support multiple device instance
Support multiple voltage ADC device instance. Clients
need to register with the voltage ADC using the device
consumer name used to associate with the corresponding
phandle of the VADC. Clients receive the device instance
which is to be used everytime an ADC request is made.
This change involves changing the interface to issue
ADC request and the corresponding clients changes.
