[1/2] dt-bindings: pinctrl: qcom: add sdm670 pinctrl

There is a new driver for the Snapdragon 670 TLMM (Top-Level Mode
Multiplexer). Document it.

Adapted from qcom,sm6350-pinctrl.yaml in the same directory at
commit c09acbc499e8 ("dt-bindings: pinctrl: use pinctrl.yaml").

You only have gpio0 through gpio149 in the implementation, so the last
15[01] is not applicable.
