s390 does not even need (in|out)b(_p|). I wondered what else from io.h
do we not need. The answer is:

We haven't required ioport implementations in the past, afaik.

devres iomap made lib/iomap.c always built and added several
arch-indep PCI routines to include/linux/io.h and lib/iomap.c without
wrapping them inside CONFIG_PCI. This breaks configurations where PCI
is not configured. Wrap pci_iomap() in CONFIG_PCI and move managed
PCI iomap functions into
