    arm64: dts: mt7622: fix BPI-R64 WPS button
    
    [ Upstream commit c98e6e683632386a3bd284acda4342e68aec4c41 ]
    
    The bananapi R64 (BPI-R64) experiences wrong WPS button signals.
    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.
    
    The official BPI-R64 sources can be found on
    https://github.com/BPI-SINOVOIP/BPI-R64-openwrt
