[Simh] PDP-8 FPP register name descriptions

[Ray Jewhurst]

I already used EK-FFP8A-MM-001 and the Handbook and could figure out about
half the registers.  I'm not by my code right now but I will send a message
listing the ones I couldn't figure out later tonight. While I was thinking
of amending the documentation to include the FFP8A.

Thanks
Ray
