m68k: Allow no CPU/platform type for allnoconfig

Allow no CPU/platform type for allnoconfig
  - Provide a dummy value for FPSTATESIZE if no CPU type was selected
  - Provide a dummy value for NR_IRQS if no platform type was selected
  - Warn the user if no CPU or platform type was selected

Note: you still cannot build an allnoconfig kernel, as CONFIG_SWAP=n doesn't
build and we cannot easily fix that
