The m68k/m68knommu merge broke the qspi build.

There is a lot of common code in the sys_m68k.c files. The mmu and non-mmu
versions can easily be merged into a single file.

There is really only 2 functions that differ in the 2 cases. A single
ifdef on CONFIG_MMU can take care of this. Alternatively we could break
those 2 functions out and maintain sys_m68k_no.c and sys_m68k_mm.c with
just this code in it (Makefile could then just build the right one).
Does anyone have strong feelings on which way they want this done?

It is strait forward to merge the mmu and non-mmu versions of

After cleaning up m68k_ksyms_no.c it is now strait forward to merge
the non-mmu and mmu versions of m68k_ksyms.c. The need for the extra
gcc functions is not strictly based on having an MMU or not. It is
based on the family the processor belongs too, so use an appropriate
conditional check.

There is no reason most of the symbols enclosed in a conditional
on CONFIG_COLDFIRE need to be exported. And they sure don't need to
be doing it in m68k_ksyms_no.c. Move the dma symbols export (which
are currently needed) to the definitions of those, and remove the
rest of the exporting here.

cpu_sibling_mask() is not defined unless CONFIG_SMP is defined, so it
must not be used directly in the code without ifdef protection.

To solve the problem and avoid ifdefs in the code, define
for_each_sibling() and use it instead.
