KVM: PPC: BookE: Improve irq inject tracepoint
When injecting an IRQ, we only document which IRQ priority (which translates to IRQ type) gets injected. However, when reading traces you don't necessarily have all the numbers in your head to know which IRQ really is meant. This patch converts the IRQ number field to a symbolic name that is in sync with the respective define. That way it's a lot easier for readers to figure out what interrupt gets injected.
