361a541dc2 m68knommu: move definition of mach_gettod to where it is used
The mach_gettod function pointer is only called from the time_no.c
code. So move its actual definition to there too. It is currently in
setup_no.c for no particularly good reason.

c06e9bb427 m68knommu: use generic section names in setup code
We should be including and using sections.h to get at the extern
definitions of the linker sections in the m68knommu startup code.
Not defining them locally.

66d857b08b m68k: merge m68k and m68knommu arch directories
There is a lot of common code that could be shared between the m68k
and m68knommu arch branches. It makes sense to merge the two branches
into a single directory structure so that we can more easily share
that common code.

This is a brute force merge, based on a script from Stephen King
<sfking@fdwdc.com>, which was originally written by Arnd Bergmann
<arnd@arndb.de>.

On top of this file merge I have done a simplistic merge of m68k and
m68knommu Kconfig, which primarily attempts to keep existing options and
menus in place. Other than a handful of options being moved it produces
identical .config outputs on m68k and m68knommu targets I tested it on.

With this in place there is now quite a bit of scope for merge cleanups
in future patches.
