[PATCH 1/3] dt-bindings: watchdog: fsl-imx: document i.MX compatibles

[Krzysztof Kozlowski]

Document all ARMv5, ARMv6 and ARMv7 i.MX compatibles used in DTSes (even
though driver binds only to fsl,imx21-wdt) to fix dtbs_check warnings
like:

  arch/arm/boot/dts/imx53-qsb.dt.yaml: gpio at 53fe0000: compatible:
    ['fsl,imx53-gpio', 'fsl,imx35-gpio'] is not valid under any of the given schemas
