r336773 removed all things xscale. However, some things xscale are
really armv5. Revert that entirely. A more modest removal will follow.
Noticed by: andrew@
The OLD XSCALE stuff hasn't been useful in a while. The original
committer (cognet@) was the only one that had boards for it. He's
blessed this removal. Newer XSCALE (GUMSTIX) is for hardware that's
quite old. After discussion on arm@, it was clear there was no support
for keeping it.

Remove all the big-endian arm architectures (ixp425 and ixp435)
support in the kernel and associated drivers.

it into pmap-v4.h where they are used. Other than those few lines of
support for different MMU types, nothing in cpuconf.h has been used in our
code for quite a while.
The file existed to set up a variety of symbols to describe the
architecture. Over the past few years we have converted all of our source
to use the new architecture symbols standardized by ARM Inc, and predefined
by both clang and gcc.

or pte-v6.h in files which needs it.
There are quite internal definitions in pte-v4.h and pte-v6.h headers
specific for corresponding pmap implementation. These headers should be
included only in very few files and an intention is to not hide for
which implementation such files are.
Further, sys/arm/arm/elf_trampoline.c is an example of file which
uses armv4 like pmap implementation for both armv4 and armv6 platforms.
This is another reason why pte.h which includes specific header
according to __ARM_ARCH is not created.
Create new pmap.h which includes specific header according to
__ARM_ARCH.
Note that <machine/pmap.h> is included from <vm/pmap.h> so one common
<machine/pmap.h> must exist.
