[PATCH v4 21/34] dt-bindings: pinctrl: qcom,msm8953: fix matching pin config

[Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>]

The TLMM pin controller follows generic pin-controller bindings, so
should have subnodes with '-state' and '-pins'.  Otherwise the subnodes
(level one and two) are not properly matched.  This method also unifies
the bindings with other Qualcomm TLMM and LPASS pinctrl bindings.
