Subject: [PATCH v2 09/12] dt-bindings: pinctrl: qcom,sm8250-lpass-lpi: fix matching pin config

The LPASS pin controller follows generic pin-controller bindings, so
just like TLMM, should have subnodes with '-state' and '-pins'.

  qcom/qrb5165-rb5.dtb: pinctrl@...0000: wsa-swr-active-pins: 'pins' is a required property
