If CONFIG_XICS is set, then smp_pSeries_cpu_bootable() is unnecessary.
As warnings are treated as errors, this fails to build.

This patch only defines smp_pSeries_cpu_bootable() when CONFIG_XICS is
set.

I'm not sure, but I would guess that was just an oversight by whoever
added the cpu_bootable check. By which I mean it should be in the mpic
ops as well - avoiding the need for any ifdefery.
