dt-bindings: mmc: mtk-sd: add tuning steps related property

Add 'mediatek,tuning-steps' setting. This property will give MSDC
a chance to extend tuning steps up to 64. With more tuning steps,
MSDC may achieve a more optimal calibration result, thus avoiding
potential CRC issues.

it is a "binding", but instead just describe the hardware.

Drop trailing "bindings" in various forms (also with trailing full

dt-bindings: mmc: mtk-sd: Set clocks based on compatible

The binding was describing a single clock list for all platforms, but
that's not really suitable:

Most platforms using at least 2 clocks (source, hclk), some of them
a third "source_cg". Mt2712 requires an extra 'bus_clk' on some of
its controllers, while mt8192 requires 8 clocks.

Move the clock definitions inside if blocks that match on the
compatibles.

I used Patch from Nícolas F. R. A. Prado and modified it to not using
"not" statement.

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:

- const: mediatek,mt8183-mmc

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.
