Different revision of i.MX8MP EVK boards may have different external pull up registor design, some are enabled while some are NOT, to make sure the WDOG_B pin works properly, better to enable internal pull up resistor. Since enabling internal pull up resistor is NOT harmful and having benefit of flexibility on different board design, just enable it for all i.MX8MP boards.
