Make trivial changes on the binding.

- Update title to include MT7531 switch.
- Add me as a maintainer. List maintainers in alphabetical order by first
name.
- Add description to compatible strings.
- Fix MCM description. mediatek,mcm is not used on MT7623NI.
- Add description for reset-gpios.
- Remove quotes from $ref: "dsa.yaml#".

Will do, thanks for the example.

Only valid for those, yes. I'll make it false in allOf:if:then for 
mediatek,mt7531. It either can or can't be used for mediatek,mt7530 so 
nothing to do there.

Thanks, I'll make it false in allOf:if:then for mediatek,mcm.
