Can't these just be in the final dts file and not in the dtsi
file? Technically the pmic pairings are a board choice and not an
SoC choice so they shouldn't be here. The msm-id properties are
a little easier to justify, but then I thought we decided to only
put them in the boards that need them?

I imagine these aren't used. Please remove them.

Just put the soc stuff here instead of having an empty node we
fill later please. That matches other qcom dtsi files.

This whole node should be outside of soc node.

Please add a trigger type and use the GIC_SPI/IRQ_TYPE_* macros.
