Fixes fp1100 regression in:

SHA-1: 907115ed06

* create c-chip device with correct CPU type in it and a bunch of notes (pinout etc.)
create a uPD78C11 derived CPU type for this purpose, with internal ROM map
use internal ROM map for other uPD78C10 chips as it's always present.
add missing NO_DUMP definitions to various games using C-Chips with correct size etc.
pump megablast through the device code as really all it ever does is bank the c-chip window and test the RAM.
