[ARM] nommu: adjust headers for !MMU ARM systems
Majorily based on Hyok Choi's patches, this fixes up the asm-arm
header files for mmuless systems. Over and above Hyok's patches:
- nommu.h merged into mmu.h (it's only a structure)
- nommu_context.h is essentially the same as mmu_context.h, but
without the MM switching code.
so there's no point having separate files. Also, in memory.h,
there's no point #ifndef'ing PHYS_OFFSET and END_MEM - both
CONFIG_DRAM_BASE and CONFIG_DRAM_SIZE will always be set by the
configuration scripts.
Other files have minor formatting changes, but are essentially
the same. Hyok's original patches were signed off thusly:
