Armin Wolf 2be5f0d753 hwmon: (sch56xx) Use devres functions for watchdog
Use devm_kzalloc()/devm_watchdog_register() for
watchdog registration since it allows us to remove
the sch56xx_watchdog_data struct from the drivers
own data structs.
Remove sch56xx_watchdog_unregister since devres
takes care of that now.
