mm: remove pte_*map_nested()
Since we no longer need to provide KM_type, the whole pte_*map_nested()
API is now redundant, remove it.

CRIS: Define io_remap_pfn_range as remap_pfn_range
CRIS don't need any special mapping for io, but didn't define this,
meaning that all uses of io_remap_pfn_range lead to compile errors.
This fixes a compile error introduced in CRIS when drivers/mtd/mtdchar.c
mmap handling was changed in commit dd02b67d5e9e7896891fa27eb5db65f55a290998

MM: Pass a PTE pointer to update_mmu_cache() rather than the PTE itself
On VIVT ARM, when we have multiple shared mappings of the same file
in the same MM, we need to ensure that we have coherency across all
copies. We do this via make_coherent() by making the pages
uncacheable.
This used to work fine, until we allowed highmem with highpte - we
now have a page table which is mapped as required, and is not available
for modification via update_mmu_cache().
Ralf Beache suggested getting rid of the PTE value passed to
update_mmu_cache():
On MIPS update_mmu_cache() calls __update_tlb() which walks pagetables
to construct a pointer to the pte again. Passing a pte_t * is much
more elegant. Maybe we might even replace the pte argument with the
pte_t?
Ben Herrenschmidt would also like the pte pointer for PowerPC:
Passing the ptep in there is exactly what I want. I want that
-instead- of the PTE value, because I have issue on some ppc cases,
for I$/D$ coherency, where set_pte_at() may decide to mask out the
_PAGE_EXEC.
So, pass in the mapped page table pointer into update_mmu_cache(), and
remove the PTE value, updating all implementations and call sites to
suit.
Includes a fix from Stephen Rothwell:

CRIS: add pgprot_noncached
On CRIS, the high address bit controls caching, which means that
we can add a pgprot_noncached() macro that sets this bit in the
address.
