[PATCH v3] ARM: dts: imx6: RDU2: disable internal watchdog

[PATCH v3] ARM: dts: imx6: RDU2: disable internal watchdog

[Andrey Smirnov]

From: Lucas Stach <l.stach-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>

The system has an external watchdog in the environment processor
so the internal watchdog is of no use.
