[M68KNOMMU]: remove cruft from setup code

[Greg Ungerer <gerg@snapgear.com>]

Clean up the m68knommu/kernel/setup.c. It is just full of old junk.

. removed unused includes
. removed unused conditional code (with unused defines)
. removed unused code
. removed unused function prototypes and variables
. remove old/wrong comments
. retabed code that was inconsistently formated
. correct copyrights
