The realview-pbx platform has an elaborate way of avoiding the use of highmem
by redefining its phys_to_virt function. In practice this doesn't help all
that much, and it gets in the way of doing multiplatform builds for
realview.
This removes the feature and kills off the mach/memory.h file for realview.
We also lose the ability to do sparsemem with this patch, but that should
be put back into place for generic multiplatform configurations, to save
a little memory on PBX.

PCI support for realview was never merged, and trying to build realview with
CONFIG_PCI enabled fails because the constants for the mapping windows are
not defined anywhere.
This removes them from the static I/O window mapping table as a preparation
for multiplatform support.

In order to move realview into multiplatform, we have to prevent device
drivers from accessing the machine header files.
In case of the clk driver, this is very simple, we just copy the
small set of register definitions into the driver that needs them.

Commit 42c4dafe803dca ("ARM: 6202/1: Do not ARM_DMA_MEM_BUFFERABLE
on RealView boards with L210/L220") changed the generic setting for
ARM_DMA_MEM_BUFFERABLE to be disabled on any Realview kernel that includes
support for any of the ARM11 variations. Doing this was required to
allow doing DMA without a lockup in the l2x0 cache controller on the
Realview platform.
Unfortunately, in a kernel that also contains support for any ARMv7
based machine, the same change makes it impossible to do DMA on ARMv7,
which gets in the way of enabling multiplatform support on Realview.
As confirmed by Catalin Marinas and Linus Walleij, the current
code for Realview that we have in the kernel does not actually
perform any DMA, and this is unlikely to change in the future.
Therefore we can revert 42c4dafe803dca without introducing regressions,
but we must never start using DMA on this platform in the future.

The realview barrier implementation tries to avoid calling outer_sync in order
to not lock up as a result of a bug in the l220 cache controller.
This gets in the way of the multiplatform support, but we can still remove
it if we make sure that the outer_sync function never gets called, by replacing
the function pointer with NULL, right after initialization.

When testing I see that this patch does not compile, but later patches
remove the offending code so it compiles again.
It needs this:

This isn't working. Even if CONFIG_ATAGS is set, none of the files
inside this ifdef $(CONFIG_ATAGS) are compiled. Does Kconfig
only support if and not ifdef?
I just removed it to get things to compile. (But sadly it doesn't
boot...)

Oh, it's a silly typo:
it should be "ifdef CONFIG_ATAGS", not "ifdef $(CONFIG_ATAGS)"
Sorry about that.

For consistency with the other platforms, this remove the CPU
selection logic in mm/Kconfig that was only used by integrator,
and adds specific options for each available core tile and core
module, which in turn select the correct CPUs.
This is consistent with the new way that we do it for realview
and all other platforms.

Now that realview and integrator always select the correct CPU
type themselves based on the core tiles, there is no need to
still have them user-visible in arch/arm/mm/Kconfig. The
ARM925T symbol has been selected by the only user for many
years, so that can be removed along with the realview and
integrator specific ones.
This also solves randconfig build problems on realview.

Nothing includes these files any more, so we can simply move them
from arch/arm/mach-realview/include/mach/ to arch/arm/mach-realview.

This patchset has problems because the boardfiles aren't really
compiled even if CONFIG_ATAGS is set. I had to apply this:

This contains multiple trivial cleanups to the realview headers:
- removing the file names from the introductory comment
- removing the uncompress.h header that is unused
- removing the irqs.h header and NR_IRQS logic that is
obsoleted by sparse IRQs
