When 'unevaluatedProperties' support is enabled, the following warnings
are generated in the mmc bindings:
Documentation/devicetree/bindings/mmc/mtk-sd.example.dt.yaml: mmc@11230000: Unevaluated properties are not allowed ('reg', 'interrupts' were unexpected)
Documentation/devicetree/bindings/mmc/sdhci-am654.example.dt.yaml: mmc@4f80000: Unevaluated properties are not allowed ('sdhci-caps-mask' was unexpected)
Documentation/devicetree/bindings/mmc/socionext,uniphier-sd.example.dt.yaml: mmc@5a400000: Unevaluated properties are not allowed ('dma-names', 'dmas' were unexpected)
Documentation/devicetree/bindings/mmc/arm,pl18x.example.dt.yaml: mmc@80126000: Unevaluated properties are not allowed ('dmas', 'dma-names' were unexpected)
Documentation/devicetree/bindings/mmc/arasan,sdhci.example.dt.yaml: mmc@80420000: Unevaluated properties are not allowed ('resets' was unexpected)
Documentation/devicetree/bindings/mmc/arm,pl18x.example.dt.yaml: mmc@52007000: Unevaluated properties are not allowed ('interrupt-names' was unexpected)
Documentation/devicetree/bindings/clock/imx8qxp-lpcg.example.dt.yaml: mmc@5b010000: Unevaluated properties are not allowed ('power-domains' was unexpected)
Add the missing properties as necessary. For pl18x, drop interrupt-names
as there isn't any use of it when there are 2 interrupts.
