pci_iounmap seems misplaced in iomap.h. Move it to where its cousins
live. Since iomap.h includes pci_iomap.h, anybody relying on getting
the declaration through iomap.h will still get it.
It would be natural to put the static inline version inside the
#elif defined(CONFIG_GENERIC_PCI_IOMAP)
Since GENERIC_IOMAP selects GENERIC_PCI_IOMAP, that would be ok for
those who select GENERIC_IOMAP. However, I fear there are some that
select GENERIC_PCI_IOMAP without GENERIC_IOMAP, and which perhaps have
their own pci_iounmap stub definition somewhere. So for now at least,
define the static inline version under the same conditions as it were
in iomap.h.
