Subject: [PATCH v1] dt-bindings: mmc: change compatiable string for MT8195 mmc host IP

MT8195 mmc host IP is compatible with MT8183, and currently it shows:
properties:
  compatible:
    oneOf:
...
      - items:
         - const: mediatek,mt8192-mmc
         - const: mediatek,mt8195-mmc
         - const: mediatek,mt8183-mmc
which means the compatible string in the device tree would be:
	compatible = "mediatek,mt8192-mmc", "mediatek,mt8195-mmc",
		     "mediatek,mt8183-mmc";
The bindings is wrong and that isn't the result we want.
instead we want:
properties:
  compatible:
    oneOf:
...
      - items:
         - const: mediatek,mt8192-mmc
         - const: mediatek,mt8183-mmc
      - items:
         - const: mediatek,mt8195-mmc
         - const: mediatek,mt8183-mmc
which would give us:
	compatible = "mediatek,mt8192-mmc", "mediatek,mt8183-mmc";
and
	compatible = "mediatek,mt8195-mmc", "mediatek,mt8183-mmc";
