The pcim_*() functions in lib/devres.c are guarded by an #ifdef CONFIG_PCI
and, thus, don't belong to this file. They are only ever used for PCI and
are not generic infrastructure.
Move all pcim_*() functions in lib/devres.c to drivers/pci/devres.c.
Adjust the Makefile.
Add drivers/pci/devres.c to Documentation.

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.

msi.c is getting larger and really could do with a splitup. Move it into
its own directory to prepare for that.

Add a new directory in the driver API guide for PCI-specific documentation.
This is in preparation for adding a new PCI P2P DMA driver writers guide
which will go in this directory.
