Add cached device type for ioremap_cached(). Group all device memory
types together, and ensure that they all have a "MT_DEVICE" prefix.

Remove fault-armv.o, mmap.o and mm-armv.o from uclinux builds - these
are concerned with MMU-ful operations, and as such are redundant for
uclinux.
Since this also removes iotable_init() and iotable_init() is used
extensively in the platform support files, just make it a no-op.
Based upon a couple of patches by Hyok.

TABLE_SIZE is never used in arch/arm/mm/init.c. create_memmap_holes(),
memtable_init, and setup_io_desc() no longer exist in the kernel.

Patch from George G. Davis
This Freescale Semiconductor, Inc. contributed patch adds mem_types[]
support for ARMv6 non-shared device memory region attributes. This
implementation provides support for only first level section mapped
non-shared devices. Second level non-shared device mappings are not
yet supported.

Patch from Deepak Saxena
In working on adding 36-bit addressed supersection support to ioremap(),
I came to the conclusion that it would be far simpler to do so by just
splitting __ioremap() into a main external interface and adding an
__ioremap_pfn() function that takes a pfn + offset into the page that
__ioremap() can call. This way existing callers of __ioremap() won't have
to change their code and 36-bit systems will just call __ioremap_pfn()
and we will not have to deal with unsigned long long variables.
Note that __ioremap_pfn() should _NOT_ be called directly by drivers
but is reserved for use by arch_ioremap() implementations that map
32-bit resource regions into the real 36-bit address and then call
this new function.

Macro arguments should _always_ be surrounded by parentheses
when used to prevent unexpected problems with operator precedence.

Patch from Deepak Saxena
Convert map_desc.physical to map_desc.pfn. This allows us to add
support for 36-bit addressed physical devices in the static maps
without having to resort to u64 variables.

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!
