gpio: Adjust of_xlate API to support multiple GPIO chips
This patch changes the of_xlate API to make it possible for multiple gpio_chips to refer to the same device tree node. This is useful for banked GPIO controllers that use multiple gpio_chips for a single device. With this change the core code will try calling of_xlate on each gpio_chip that references the device_node and will return the gpio number for the first one to return 'true'.
