m68k/sun3: Remove unselectable code in prom_init()
This was copied from SPARC, but isn't relevant for the supported Sun-3 models. [Geert] Also remove the related extern declarations, and update the comment about prom_init(). Reported-by: Sarah Nadi <snadi@uwaterloo.ca> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
