dt-bindings: pinctrl: qcom,ipq6018: fix matching pin config

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.
