> The DT of_device.h and of_platform.h date back to the separate

> As part of that merge prepping Arm DT support 13 years ago, they
> "temporarily" include each other. They also include platform_device.h
> and of.h. As a result, there's a pretty much random mix of those include
> files used throughout the tree. In order to detangle these headers and
> replace the implicit includes with struct declarations, users need to
