    mt7620: fix missing kernel config symbol
    
    Fixes following missing kernel config symbol after adding GPIO watchdog:
    
      Software watchdog (SOFT_WATCHDOG) [M/n/y/?] m
      Watchdog device controlled through GPIO-line (GPIO_WATCHDOG) [Y/n/m/?] y
        Register the watchdog as early as possible (GPIO_WATCHDOG_ARCH_INITCALL) [N/y/?] (NEW)
    
    Fixes: 1a97c03d864e ("rampis: feed zbt-we1026 external watchdog")

    [adapted to config-5.4]
