m68k: MOVEC insn. should generate exception if wrong CR is accessed

Browse source 
Add CPU class detection for each CR type in the m68k_move_to/from helpers,
so that it throws and exception if an unsupported register is requested
for that CPU class.

Reclassified MOVEC insn. as only supported from 68010.
