[PATCH v3 2/5] dt-bindings: soc: fsl: layerscape-dcfg: add the LX2160A pad-mux child

[Vincent Jardin via B4 Relay]

From: Vincent Jardin <vjardin@xxxxxxx>

On the LX2160A the DCFG node holds the pad mux, overridden through its
DCSR view. Allow fsl,lx2160a-dcfg with simple-mfd, so that the child is
populated, and the pinctrl child, on the LX2160A only.
