The AD7266 have no in-tree users making use of the platform data mechanism to pass address GPIO lines when not using a fixed address, so we can easily convert this to use GPIO descriptors instead of the platform data integers currently passed. Lowercase the labels "ad0".."ad2" as this will make a better fit for platform descriptions like device tree that prefer lowercase names such as "ad0-gpios" rather than "AD0-gpios". Board files and other static users of this device can pass the same GPIO descriptors using machine descriptor tables if need be.
