Subject[PATCH 5/7] watchdog: mtk: allow setting timeout in devicetree
Date
watchdog_init_timeout() will allways pick timeout_param since it
defaults to a valid timeout.

By following best practice described in
Documentation/watchdog/watchdog-kernel-api.txt, it also
let us to set timout-sec property in devicetree.
