Greg Ungerer ece9ae6515 m68k: fix crufty ColdFire intro comments
Quite a few of the ColdFire specific support files have a pathname in the
title comments of the file. These files have moved around a bit over the
years, and most are no longer accurate. Remove the pathname and fix the
comments to include at least a short description of the files contents.
