[PATCH] powerpc: Move xics.[ch] into platforms/pseries
This patch moves the XICS interrupt controller code into the
platforms/pseries directory, since it only appears on pSeries
machines. If it ever appears on some other machine we can move it to
sysdev, although xics.c itself will need a bunch of changes in that
case to remove pSeries specific assumptions.
