[PATCH] m68knommu: cleanup setup.c

Browse source 
A cleanup of m68knommu/kernel/setup.c :

- No need to initialize global pointers to NULL, they will have that value
  automatically, and they eat up space in my data segment image in FLASH.
- Remove get_cpuinfo.  It has been replaced by show_cpuinfo.
