x86, NMI: Add priorities to handlers
In order to consolidate the NMI die_chain events, we need to setup the priorities for the die notifiers. I started by defining a bunch of common priorities that can be used by the notifier blocks. Then I modified the notifier blocks to use the newly created priorities. Now that the priorities are straightened out, it should be easier to remove the event DIE_NMI_IPI.
