Subject: [PATCH v3 17/17] dt-bindings: pinctrl: qcom,sc7280: use common TLMM pin schema

The common Qualcomm TLMM pin controller schema for pin mux and config
already brings requirement of function for gpio pins and the definition
of drive-strength.

Acked-by: Rob Herring <robh@...nel.org>

Changes since v2:
1. Drop drive-strength, reword commit msg.
2. Add tags.
