m68knommu: cleanup 68360 startup code
Clean up 68360 timer support code. Removed header includes not needed. Remove use of old m68knommu timer function pointers. Use common function naming for 68328 timer functions. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
