trace,x86: Move creation of irq tracepoints from apic.c to irq.c
Compiling without CONFIG_X86_LOCAL_APIC set, apic.c will not be
compiled, and the irq tracepoints will not be created via the
CREATE_TRACE_POINTS macro. When CONFIG_X86_LOCAL_APIC is not set,
we get the following build error:
LD init/built-in.o

make[1]: *** [vmlinux] Error 1
make: *** [sub-make] Error 2
As irq.c is always compiled for x86, it is a more appropriate location
to create the irq tracepoints.
