A new series updating the ov2680 driver is pending upstream now and in this series the ov2680 driver is patched to look for "powerdown" as con-id, instead of relying on GPIO remapping in the int3472 code, so the GPIO remapping is no longer necessary.

The INT3472 device is going to be the only supplier of a regulator for the sensor device. So there is no chance of collisions with other regulator suppliers and it is undesirable to need to manually add new entries to int3472_sensor_configs[] for each new sensor module which uses a GPIO regulator. Instead just always use "avdd" as supply-id when registering the GPIO regulator. If necessary for specific sensor drivers then other supply-ids can be added as aliases in the future, adding aliases will be safe since INT3472 will be the only regulator supplier for the sensor.
