In OpenWrt pushing the WPS button while powering on the device will set it to recovery mode. Currently, this also happens without any user interaction. In particular, the wrong signals appear while booting the device or restarting it, e.g. after doing a system upgrade. If the device is in recovery mode the user needs to manually power cycle or restart it. The official BPI-R64 sources set the WPS button to GPIO_ACTIVE_LOW in the device tree. This setting seems to suppress the unwanted WPS button press signals. So this commit changes the button from GPIO_ACTIVE_HIGH to GPIO_ACTIVE_LOW.
