Add prot_pte_ext to the mem_types table to allow the extended pte
attributes to be passed to set_pte_ext(), thereby permitting us to
specify memory type information for the hardware PTE entries.

We really want to be using the memory type table in ioremap, so we
only have to do the CPU type fixups in one place.

If we're going to have mmu.c for code which is specific to the MMU
machines, we might as well move the other MMU initialisation
specific code from mm-armv.c into this new file.  This also allows
us to make some functions static.

Move the MMU specific code from init.c into mmu.c, and add nommu
fixups to nommu.c

Move top_pmd into arch/arm/mm/mm.h - nothing outside arch/arm/mm
references it.

Move the repeated definition of TOP_PTE into mm/mm.h, as well as
a few function prototypes.
