m68knommu: factor more common ColdFire cpu reset code
Most of the more modern ColdFire cores use the same code to reset the CPU
(but it is different to most of the earlier cores). Currently that is
duplicated in each of the sub-arch files. Pull out this common code and
out a single copy of it with the other common reset code.

m68knommu: factor some common ColdFire cpu reset code
A number of the early ColdFire cores use the same code to reset the CPU.
Currently that is duplicated in each of the sub-arch files. Pull out this
common code and use a single copy of it for all CPU types that use it.

m68knommu: merge common ColdFire UART platform setup code
The ColdFire UART is common to all ColdFire CPU's. No need to duplicate
its platform setup code for every CPU family member. Merge all the setup
code into a single shared file.

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>.
> The script was inspired by the script Sam Ravnborg used to merge the
> includes from m68knommu. For those files common to both arches but
> differing in content, the m68k version of the file is renamed to
> <file>_mm.<ext> and the m68knommu version of the file is moved into the
> corresponding m68k directory and renamed <file>_no.<ext> and a small
> wrapper file <file>.<ext> is used to select between the two version. Files
> that are common to both but don't differ are removed from the m68knommu
> tree and files and directories that are unique to the m68knommu tree are
> moved to the m68k tree. Finally, the arch/m68knommu tree is removed.
>
> To select between the the versions of the files, the wrapper uses
>
> #ifdef CONFIG_MMU
> #include <file>_mm.<ext>
> #else
> #include <file>_no.<ext>
> #endif
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.
