pseries: Split xics irq configuration from state information
Currently the XICS irq controller code has a per-irq state structure which
amongst other things includes whether the interrupt is level or message
triggered - this is configured by the platform code, and is not directly
visible to the guest. This leads to a slightly awkward construct at reset
time where we need to reset everything in the state structure except the
lsi/msi flag, which needs to retain the information given at platform init
time.
More importantly this flag will make matching the qemu state to the KVM
state for the upcoming in-kernel XICS implementation more awkward. This
patch, therefore, removes this flag from the per-irq state structure,
instead adding a parallel array giving the lsi/msi configuration per irq.
