dm: gpio: Allow gpio command to adjust GPIOs that are busy The gpio command mostly relies on gpio_request() and gpio_free() being nops, in that you can request a GPIO twice. With driver model this is now implemented correctly, so it fails. Change the command to deal with a failure to claim the GPIO. Signed-off-by: Simon Glass <sjg@chromium.org>
