[PATCH v2 1/2] dt-bindings: watchdog: fsl-imx: document NXP compatibles

[Krzysztof Kozlowski]

Document all ARMv5, ARMv6, ARMv7 and ARMv8 NXP (i.MX, Layerscape)
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

Signed-off-by: Krzysztof Kozlowski <krzk at kernel.org>

Changes since v1:
1. Add also Layerscape,
2. Add Rob's review tag.
