ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe: the
buffer doesn't share a cache with the others.

MN10300 arch headers and place them instead in the same directories as contain
the .c files for the processor and unit implementations.
This permits the symlinks include/asm/proc and include/asm/unit to be
dispensed with. This does, however, require that #include <asm/proc/xxx.h> be
converted to #include <proc/xxx.h> and similarly for asm/unit -> unit.
