This patch follows the other patches that added the watchdog
core to various (armvirt, malta, ath79, ...) targets that
have been hit by the following build error:
Package kmod-hwmon-sch5627 is missing dependencies for the following libraries:
watchdog.ko
In theory, we could have just added the CONFIG_WATCHDOG_CORE=y
to the Kconfig variable of kmod-hwmon-sch5627's package definition.
This would have forced the watchdog core to be builtin and less
architectures would need to be updated. But we might as well follow
through here.
