This does a sweeping change fixing up all the missing system_misc.h and system_info.h includes from the system.h split-up change. These were the ones I came across when building all defconfigs in arch/arm/configs, there might be more but they lack adequate build coverage to be easily caught. I'm expecting to get a lot of these piecemeal by each maintainer, so we might just as well do one sweeping change to get them all at once.
