[PATCH v4 01/22] dt-bindings: mux: Remove nodename pattern constraints

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.
