arm64: dts: qcom: msm8994: Modernize the DTS style

Following changes have been made:

- remove name, compatible and msm-id
- wrap clocks in clocks{}
- order nodes by name and by address
- clock_gcc -> gcc
- msmgpio -> tlmm
- qcom,smem -> smem
- remove unit-address from smem
- retire msm8994-pins.dtsi
- add some of the missing pins
- make comments C-style
