arm64: dts: qcom: msm8916: Drop msm8916-pins.dtsi

MSM8916 and MSM8939 are pin-compatible and should have exactly the same
pinctrl definitions. Still, having pinctrl separated to a -pins.dtsi
is not typical anymore for Qualcomm platforms upstream. Since Bjorn
specifically requested having the MSM8939 pinctrl inside msm8939.dtsi
lets move the MSM8916 definitions to msm8916.dtsi as well to have
a consistent location.

While at it sort the nodes and drop unnecessary empty lines.

Note that in almost all cases changes to MSM8916 pinctrl should also be
applied to MSM8939 pinctrl (and vice versa). Right now they are back in
sync again and completely identical.
