bsp: cvitek: remove warning when building wdt driver

```
./bsp/cvitek/drivers/drv_wdt.c: In function '_wdt_control':
warning: assignment to 'void *' from 'unsigned int' makes pointer
from integer without a cast [-Wint-conversion]
  119 |         wdt_device->parent.user_data = (rt_uint32_t)(*(rt_uint32_t *)arg);
      |                                      ^
warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  122 |         *(rt_uint32_t *)arg = (rt_uint32_t)wdt_device->parent.user_data;
      |                               ^
```

Rootcasue: It's not portable to store integar in a pointer.

Solution: use global _wdt_dev to store the timeout value.
