[PATCH 1/4] lib: move pci_iomap.c to drivers/pci/

[Philipp Stanner <pstanner@redhat.com>]

This file is guarded by an #ifdef CONFIG_PCI. It, consequently, does not
belong to lib/ because it is not generic infrastructure.

Move the file to drivers/pci/ and implement the necessary changes to
Makefiles and Kconfigs.
