Currently we only provide an implementation of smp_timer_broadcast in

smp_timer_broadcast is only used in smp.c, smp.c depends on SMP, and
GENERIC_CLOCKEVENTS_BROADCAST is selected by SMP, this is unnecessary.
This patch removes the redundant guard.

CONFIG_GENERIC_CLOCKEVENTS_BROADCAST isn't mandatory to
have SMP kernel working so the below select in ARM arch
kconfig not seems to entirely accurate. SMP kernel will
still boot with !GENERIC_CLOCKEVENTS_BROADCAST.
select GENERIC_CLOCKEVENTS_BROADCAST if SMP
The issue comes only for deeper CPU power C-states.
Anyway, you patch is correct from the current code point of
view.
