[PATCH v4 2/2] dt-bindings: mfd: update TI tps6105x chip bindings

[Sven Van Asbroeck <thesven73@gmail.com>]

The driver has been extended to optionally get its operational
mode, regulator init data and led naming from the devicetree.

+Optional sub-node:
+
+This subnode selects the chip's operational mode.
+There can be at most one single available subnode.
+
+- regulator: presence of this sub-node puts the chip in regulator mode.
+	see Documentation/devicetree/bindings/regulator/regulator.txt
+
+- led: presence of this sub-node puts the chip in led mode.
+	Optional properties:
