ARM: dts: msm: Reorganize the pinctrl node

As the size of the lahaina-pinctrl.dtsi file is huge, it's
possible that the config nodes might be placed incorrectly
under &soc{..}, instead of &tlmm{..} due to human errors.
Hence, rearrange the node such that the lahaina-pinctrl.dtsi
file itself begin with the &tlmm block to minimize these errors.
