[RFC PATCH 1/5] ARM: remove useless guard in smp.c

[Mark Rutland]

Currently we only provide an implementation of smp_timer_broadcast in
smp.c if GENERIC_CLOCKEVENTS_BROADCAST is selected. As
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.
