Now we can use FD_STATUS and FD_DATA instead of 4 or 5, let's do
this, and also use STATUS_DMA and STATUS_READY for the status bits.

Currently we have architecture-specific fd_inb() and fd_outb() functions
or macros, taking just a port which is in fact made of a base address and
a register. The base address is FDC-specific and derived from the local or
global "fdc" variable through the FD_IOPORT macro used in the base address
calculation.
This change splits this by explicitly passing the FDC's base address and
the register separately to fd_outb() and fd_inb(). It affects the
following archs:
- x86, alpha, mips, powerpc, parisc, arm, m68k:
simple remap of port -> base+reg
- sparc32: use of reg only, since the base address was already masked
out and the FDC controller is known from a static struct.
- sparc64: like x86 for PCI, like sparc32 for 82077
Some archs use inline functions and others macros. This was not
unified in order to minimize the number of changes to review. For the
same reason checkpatch still spews a few warnings about things that
were already there before.
The parisc still uses hard-coded register values and could be cleaned up
by taking the register definitions.
The sparc per-controller inb/outb functions could further be refined
to explicitly take an FDC register instead of a port in argument but it
was not needed yet and may be cleaned later.

This patch proposes to remove the IRQF_DISABLED flag from m68k architecture
code. It's a NOOP since 2.6.35 and it will be removed one day.

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.
