    ipq806x: enable gpio watchdog support
    
    The kernel driver gpio-wdt or the userspace tool om-watchdog can be used to
    trigger external gpio watchdog chips. The gpio-wdt driver has the benefit
    that it can be configured together with the rest of the device in the DTS
    and better integrates in the OpenWrt via procd.
