sched: fix hrtick & generic-ipi dependency
Andrew Morton reported this s390 allmodconfig build failure:
kernel/built-in.o: In function `hrtick_start_fair':
sched.c:(.text+0x69c6): undefined reference to `__smp_call_function_single'
the reason is that s390 is not a generic-ipi SMP platform yet, while
the hrtick code relies on it. Fix the dependency.
