Add to the max9286 driver support for parsing the newly introduced property and use it if available in place of the usual supply, as it is not possible to establish one as consumer of the max9286 gpio controller. If the new property is present, no gpio controller is registered and 'poc-supply' is ignored. In order to maximize code re-use, break out the max9286 gpio handling function so that they can be used by the gpio controller through the gpio-consumer API, or directly by the driver code. Wrap the power up and power down routines to their own function to be able to use either the gpio line directly or the supply. This will make it easier to control the remote camera power at run time.
