Currently "timeout-sec" Device Tree property is being silently ignored:
even though watchdog_init_timeout() is being used, the driver always passes
"heartbeat" == DEFAULT_HEARTBEAT == 60 as argument.

Fix this by setting struct watchdog_device::timeout to DEFAULT_HEARTBEAT
and passing real module parameter value to watchdog_init_timeout() (which
may now be 0 if not specified).
