Atari ROM port ISA adapter support for EtherNEC and NetUSBee adapters

16 bit access for ROM port adapters follows debugging and
clarification by David Galvez <dgalvez75@gmail.com>. The NetUSBee
ISP1160 USB chip uses these macros.

Basic set of definitions and support code required to turn on CONFIG_PCI
for the m68k architecture. Nothing specific to any PCI implementation in
any m68k class CPU hardware yet.

drivers/usb/musb/musb_io.h provides default implementations for
{read,write}s[bwl]() on most platforms, some of which will conflict soon
with platform-specific counterparts on m68k.

To avoid having to add more platform-specific checks to musb_io.h later,
make sure {read,write}s[bwl]() are always defined on m68k, and disable the
default implementations in musb_io.h on m68k, like is already done for
several other architectures.

On m68k, I/O macros like inb() outw() etc. are only defined to
something useful if CONFIG_ISA is set; dummies are in place if
not, but four macros were missing from the !CONFIG_ISA case.
Adding these makes some drivers, such as speakup, compile again.

Merge header files for m68k and m68knommu to the single location:

    arch/m68k/include/asm

The majority of this patch was the result of the
script that is included in the changelog below.

The script was originally written by Arnd Bergman and
exten by me to cover a few more files.

When the header files differed the script uses the following:

The original m68k file is named <file>_mm.h  [mm for memory manager]
The m68knommu file is named <file>_no.h [no for no memory manager]

The files uses the following include guard:

This include gaurd works as the m68knommu toolchain set
the __uClinux__ symbol - so this should work in userspace too.

Merging the header files for m68k and m68knommu exposes the
(unexpected?) ABI differences thus it is easier to actually
identify these and thus to fix them.

The commit has been build tested with both a m68k and
a m68knommu toolchain - with success.

The commit has also been tested with "make headers_check"
and this patch fixes make headers_check for m68knommu.

The *_ISA type defines are quite generic and cause namespace conflicts
(e.g. with `AMIGAHW_DECLARE(GG2_ISA)' in <asm/amigahw.h>) for some kernel
configurations. Use ISA_TYPE_* to avoid such conflicts.

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes.  Originally it was basically the raw
MIPS low level cache API exported to the entire world.  The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync.  So
remove it rsp.  turn the surviving bits back into an arch private API, as
discussed on linux-arch.

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!
