The nodename pattern in  created an unnecessary restriction that forced
all mux nodes to be named with the 'mux-controller' prefix.
This prevented valid use cases where mux functionality is part of other
hardware blocks that should use more specific naming conventions.

Remove the $nodename pattern constraints from both the 'select' keyword
and the properties section of the mux-controller schema.

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/d0518a64bac31a5a755471f79d6000aa81657503.1764241212.git.tommaso.merciai.xr@bp.renesas.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
