Axel Haslam 993dc992f2 greybus: gpio: Add runtime_pm suppourt ... Add runtime pm support for the gpio driver. Since there is no remote wakeup support, the module will not suspend as long as a gpio is requested. Maybe an optimization could be made, to allow suspend if all the requested gpios are in output mode, since the bridge should maintain the state of the gpio during suspend. Testing Done: using the test board, let the gpbrige enter standby and request a gpio.
