Many architectures want a generic pci_iomap but
not the rest of iomap.c. Split that to a separate .c
file and add a new config symbol. select automatically
by GENERIC_IOMAP.

When CONFIG_PCI is not enabled, CONFIG_EISA=y, and CONFIG_GENERIC_IOMAP=y,
drivers/net/3c59x.c build fails due to a recent small change to
<asm-generic/iomap.h> that surrounds pci_iomap() and pci_iounmap() with
#ifdef CONFIG_PCI/#endif.

Since that patch to iomap.h looks correct, add stubs for pci_iomap() and
pci_iounmap() with CONFIG_PCI is not enabled to fix the build errors.

x86 has ioremap_wc for wc remap. Also introduce a generic ioremap_wc
aliased to ioremap_uc so that drivers can use this interface transparently.

In the new io infrastructure, all of our operators are expecting the
underlying device to be little endian (because the PCI bus, their main
consumer, is LE).

However, there are a fair few devices and busses in the world that are
actually Big Endian.  There's even evidence that some of these BE bus and
chip types are attached to LE systems.  Thus, there's a need for a BE
equivalent of our io{read,write}{16,32} operations.

The attached patch adds this as io{read,write}{16,32}be.  When it's in,
I'll add the first consume (the 53c700 SCSI chip driver).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
