Thanks for doing this. However, some files (example below) have the
#include removed, but still use macros/symbols from arch/io.h. I think
it's best not to rely on having the appropriate headers included
indirectly, so removing #includes in header files won't break other
files.

`PNP_DEV`, for example, is used in this file, but only defined in
arch/io.h.
