lib: use generic pci_iomap on all architectures

Many architectures don't want to pull in iomap.c,
so they ended up duplicating pci_iomap from that file.
That function isn't trivial, and we are going to modify it
https://lkml.org/lkml/2011/11/14/183
so the duplication hurts.

This reduces the scope of the problem significantly,
by moving pci_iomap to a separate file and
referencing that from all architectures.
