powerpc: mpc85xx: generic timer sync is no more needed

Now in all socs which require timebase sync we have guts based
timer sync mechanism and we should not use be using generic timebase
sync anymore.

This patch removes the generic timbase sync for KEXEC also
as this can also use same guts based timebase sync.
