bsp: cvitek: fix the wdt timeout unit problem

See `components/drivers/include/drivers/watchdog.h`

maco definition of
RT_DEVICE_CTRL_WDT_GET_TIMEOUT
RT_DEVICE_CTRL_WDT_SET_TIMEOUT
RT_DEVICE_CTRL_WDT_GET_TIMELEFT

The wdt timeout time unit is defined as seconds in the API, but
the code incorrectly uses ms.

Correct this and comply with the API definition.
