PCI: Move pci_iomap.c to drivers/pci/
The entirety of pci_iomap.c is guarded by an #ifdef CONFIG_PCI. It,
consequently, does not belong to lib/ because it is not generic
infrastructure.
Move pci_iomap.c to drivers/pci/ and implement the necessary changes to
Makefiles and Kconfigs.
Update MAINTAINERS file.
Update Documentation.
