watchdog: JZ4740: Drop module remove function
When the watchdog was configured for nowayout, and after the userspace watchdog daemon closed the dev node without sending the magic character, unloading this module stopped the watchdog hardware, which was clearly a problem. Besides, unloading the module is not possible when the userspace watchdog daemon is running, so it's safe to assume that we don't need to stop the watchdog hardware in the jz4740_wdt_remove() function. For this reason, the jz4740_wdt_remove() function can then be dropped alltogether.
