[PATCH RESEND V4 1/3] dt-bindings: watchdog: move i.MX system controller watchdog binding to SCU

[Anson Huang <anson.huang@nxp.com>]

i.MX system controller watchdog depends on SCU driver to support
interrupt function, so it needs to be subnode of SCU node in DT,
binding doc should be moved to fsl,scu.txt as well.

-* Freescale i.MX System Controller Watchdog
-
-i.MX system controller watchdog is for i.MX SoCs with system controller inside,
-the watchdog is managed by system controller, users can ONLY communicate with
-system controller from secure mode for watchdog operations, so Linux i.MX system
-controller watchdog driver will call ARM SMC API and trap into ARM-Trusted-Firmware
-for watchdog operations, ARM-Trusted-Firmware is running at secure EL3 mode and
-it will request system controller to execute the watchdog operation passed from
-Linux kernel.

-Required properties:
-- compatible:	Should be :
-		"fsl,imx8qxp-sc-wdt"
