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)
