M68k Kconfig:
  - Make MMU configurable
  - Add FPU configuration
  - Add support for 68000/68008, 68010/68012, and CPU32 (embedded cores)
  - Add NOMMU configuration as a short-hand for !MMU (handy for Makefile lists)
  - 68000, 68010, and CPU don't support the CAS (Compare And Swap) instruction,
    so disable RMW_INSNS
  - Currently we support one chunk of memory only for MMUless configs
