tracing: fix build failure on s390

Browse Source 
"tracing: create automated trace defines" causes this compile error on s390,
as reported by Sachin Sant against linux-next:

 kernel/built-in.o: In function `__do_softirq':
 (.text+0x1c680): undefined reference to `__tracepoint_softirq_entry'

This happens because the definitions of the softirq tracepoints were moved
from kernel/softirq.c to kernel/irq/handle.c. Since s390 doesn't support
generic hardirqs handle.c doesn't get compiled and the definitions are
missing.

So move the tracepoints to softirq.c again.

[ Impact: fix build failure on s390 ]
