[PATCH v10 03/14] powerpc/vas: Alloc and setup IRQ and trigger port address

Allocate a xive irq on each chip with a vas instance. The NX coprocessor raises a host CPU interrupt via vas if it encounters page fault on user space request buffer. Subsequent patches register the trigger port with the NX coprocessor, and create a vas fault handler for this interrupt mapping.
