Subject: [PATCH v3 05/14] dt-bindings: watchdog: fsl-imx-wdt: Add i.MX 8M compatibles

DTSes with new i.MX 8M SoCs introduce their own compatibles so add them
to fix dtbs_check warnings like:

  arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dt.yaml: watchdog@...80000:
    compatible:0: 'fsl,imx8mm-wdt' is not one of ['fsl,imx21-wdt']
    From schema: Documentation/devicetree/bindings/watchdog/fsl-imx-wdt.yaml

  arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dt.yaml: watchdog@...80000:
    compatible: ['fsl,imx8mm-wdt', 'fsl,imx21-wdt'] is too long

  arch/arm64/boot/dts/freescale/imx8mm-var-som-symphony.dt.yaml: watchdog@...80000:
    compatible: Additional items are not allowed ('fsl,imx21-wdt' was unexpected)
