The WDOG_B is connected to external PMIC, so set "fsl,ext-reset-output"
to enable triggering PMIC reset.

The MX93_PAD_WDOG_ANY__WDOG1_WDOG_ANY pinctrl is missing, no?
Same for the other boards.

I think it should be already set in uboot. Otherwise if system halt before
kernel pin-mux driver probe, Wdog will not reset board.

Anyways, add pinctrl have not harmful here.
