2fee14ac97 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";

972d6a7dce dt-bindings: Drop redundant minItems/maxItems 
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.

This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.
