Subject: [PATCH v12 2/5] dt-bindings: mediatek: Update mmsys binding to reflect it is a system controller

The mmsys system controller is not only a pure clock controller, so
update the binding documentation to reflect that apart from providing
clocks, it also provides routing and miscellaneous control registers.
