Revamped and refactored the Compaq AT clone code, including a more correct Plasma emulation and undev branch the Deskpro 386 while adding the September 1986 and January 1988 bioses.
Added Compaq AT KBC strictly for the Deskpro 386 with the right settings, including the FPU bit.
The generic AMI/Quadtel/Phoenix IBM AT's don't issue the speed problems of the pure IBM AT beyond 8Mhz, so don't limit them to 8Mhz.
