Introducing the wdog support is for psci reset usage.
To i.MX6/7, when `reboot`, need wdog to trigger soc reset
or send out signal to pmic through wdog pin to trigger pmic reset.
In linux device tree, there is a "fsl,ext-reset-output" property, this
driver is to check whether the wdog node contains the property or not,
then decide how to trigger reset.
We still rely on normal world to initialize wdog and configure pinmux
when need to trigger pmic reset.
