watchdog: s3c2410_wdt: Use devm_add_action_or_reset() to disable watchdog
Use devm_add_action_or_reset() to disable the watchdog when the driver
is removed to simplify the code. With this in place, we can use
devm_watchdog_register_device() to register the watchdog, and the removal
function is no longer necessary.
