Add a YAML documentation for Mediatek, which uses ti reset-controller
driver directly. The TI reset controller provides a common reset management,
and is suitable for Mediatek SoCs.

My bot found errors running 'make dt_binding_check' on your patch:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/reset/mediatek-syscon-reset.example.dt.yaml: example-0: infracfg@10001000:reg:0: [0, 268439552, 0, 4096] is too long
From schema: /usr/local/lib/python3.8/dist-packages/dtschema/schemas/reg.yaml
See https://patchwork.ozlabs.org/patch/1373428
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:
pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade
Please check and re-submit.
