arm/dt: msm: Move I/O devices to a dedicated SoC node
The Device Tree specification suggests that memory-mapped
I/O devices should be declared within the 'soc' node rather
than being declared at the root level. Refactor the MSM
device tree files to follow to this design pattern.
Furthermore, declaring I/O devices with the 'soc' node
facilitates reuse of common DTSI files across device trees
whose root-level #address-cells and #size-cells properties
might be different.
Explicitly call of_platform_populate on the /soc node to
parent its devices to the root node, to preserve the kernel
ABI until userspace is updated.
