Without CONFIG_OF, the driver fails to link:
drivers/watchdog/built-in.o: In function `bcm2835_power_off':
bcm2835_wdt.c:(.text+0x1946): undefined reference to `of_find_device_by_node'
This adds a new dependency, to allow the COMPILE_TEST check to succeed.
Fixes: da2a68b3eb47 ("watchdog: Enable COMPILE_TEST where possible")
