watchdog: ebc-c384_wdt: Utilize devm_ functions in driver probe callback
The devm_ resource manager functions allow memory to be automatically released when a device is unbound. This patch takes advantage of the resource manager functions and replaces the watchdog_register_device call with the devm_watchdog_register_device call. In addition, the ebc_c384_wdt_remove function has been removed as no longer necessary due to the use of the relevant devm_ resource manager functions.
