[PATCH 3/7] dt-bindings: mailbox: fsl,mu: Use unevaluatedProperties

[Krzysztof Kozlowski]

Additional properties actually might appear (e.g. power-domains) so use
unevaluatedProperties to fix dtbs_check warnings like:

  arch/arm64/boot/dts/freescale/imx8qxp-mek.dt.yaml:
    mailbox at 5d280000: 'power-domains' does not match any of the regexes: 'pinctrl-[0-9]+'
