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.
