Patch: Add support for XGATE CPU and update M68HCS12X port

[Sean Keys]

Hi guys,
I noticed that my earlier patch included change log entries so I removed 
those and have included them as a separate plain text file with a new 
patched updated onto the latest from CVS a couple of hours ago. I hope 
that makes it easier for you to apply. Sorry for the mistake.

Thanks,
Sean
