Subject: [PATCH v2 5/6] arm64: dts: qcom: msm8916: Drop generic UART
pinctrl templates
Remove the generic UART pinctrl templates from msm8916.dtsi and copy the
definition for the custom UART use cases into the board DT files. This
makes it clear that the set of pins/pull etc are specific to the board and
UART use case.
No functional change.
