* How should CPU0 event-channel notifications be delivered?
* val[63:56] == 0: val[55:0] is a delivery GSI (Global System Interrupt).
* val[63:56] == 1: val[55:0] is a delivery PCI INTx line, as follows:
* Domain = val[47:32], Bus = val[31:16],
* DevFn = val[15: 8], IntX = val[ 1: 0]
* If val == 0 then CPU0 event-channel notifications are not delivered.
