Subject: [PATCH 2/2] dt-bindings: display: sii902x: Add supply bindings

The sii902x chip family requires IO and core voltages to reach the
correct voltage before chip initialization. Add binding for describing
the two supplies.

It is not mandatory but encouraged to convert a binding to DT schema
format before updating it. This is in order to reach a point
in time where all bindings are in DT Schema format thus
allowing much better verification of the DT files.
