    powerpc/pseries: Fix getting the server number size · 1ef8014d

    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.
