Subject: [PATCH 1/6] dt-bindings: mfd: ti,j721e-system-controller: Fix mux node errors

The ti,j721e-system-controller binding does not follow the standard mux
controller node name 'mux-controller' and the example is incomplete. Fix
these to avoid schema errors before the mux controller binding is
converted to schema.
