watchdog: pika_wdt: add __ro_after_init to ident
The object ident of type watchdog_info structure is not modified after getting initialized by pikawdt_init. Apart from getting referenced in init it is also passed as an argument to the function copy_to_user but this argument is of type const void *. Therefore add __ro_after_init to its declaration.
