pseries: Move XICS initialization before cpu initialization
Currently, the pseries machine initializes the cpus, then the XICS
interrupt controller. However, to support the upcoming in-kernel XICS
implementation we will need to initialize the irq controller before the
vcpus. This patch makes the necesssary rearrangement. This means the
xics init code can no longer auto-detect the number of cpus ("interrupt
servers" in XICS terminology) and so we must pass that in explicitly from
the platform code.
