Grant Likely 3d0f7cf0f3 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'.

Grant Likely f141ed65f2 gpio: Move DT support code into drivers/gpio
The code in drivers/of/gpio.c isn't shared by any other subsystem since it
is all gpiolib specific.  drivers/gpio is a better place to maintain these
functions.
