powerpc/85xx: Add back condition for smp
The timebase synchronization is only necessary if we need to reset a
separate core. Currently only KEXEC and CPU hotplug require resetting
a single core. The following code should be in the condition of
CONFIG_KEXEC or CONFIG_HOTPLUG_CPU
.give_timebase = smp_generic_give_timebase,
.take_timebase = smp_generic_take_timebase,
