Added removal of the fsl,ext-reset-output property in the wdog node for board revisions that pre-date the addition of the external watchdog reset signal.
This property is a recent addition to mainline linux kernel in order to specify that the IMX watchdog external reset should be used instead of the internal chip-level reset.
