m68k: move coldfire platform code
Move the m68k ColdFire platform support code directory to be with the existing m68k platforms. Although the ColdFire is not a platform as such, we have always kept all its support together. No reason to change that as this time. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
