The 'ibm,interrupt-server#-size' properties are not in the cpu nodes, which is where we currently look for them, but rather live under the interrupt source controller nodes (which have "ibm,ppc-xics" in their compatible property). This moves the code that looks for the ibm,interrupt-server#-size properties from xics_update_irq_servers() into xics_init_IRQ(). Also this adds a check for mismatched sizes across the interrupt source controller nodes. Not sure this is necessary as in this case the firmware might be seriously busted. This property only appears on POWER6 boxes and is only used in the set-indicator(gqirm) call, and apparently firmware currently ignores the value we pass. Nevertheless we need to fix it in case future firmware versions use it.
