powerpc: Fix SMP build with disabled CPU hotplugging.
Compiling 2.6.33 with SMP enabled and HOTPLUG_CPU disabled gives me the
following link errors:
LD init/built-in.o
LD .tmp_vmlinux1
arch/powerpc/platforms/built-in.o: In function `.smp_xics_setup_cpu':

make: *** [.tmp_vmlinux1] Error 1
The following change fixes that for me and seems to work as expected.
