[PATCH v3 28/34] dt-bindings: pinctrl: qcom,sdx55: 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.

qcom-sdx55-telit-fn980-tlb.dtb: pinctrl@f100000: 'pcie_ep_clkreq_default', 'pcie_ep_perst_default', 'pcie_ep_wake_default' do not match any of the regexes: '-pins$', 'pinctrl-[0-9]+'

This method also unifies the bindings with other Qualcomm TLMM and LPASS
pinctrl bindings.
