[RFC PATCH 10/13] target/ppc: remove unused interrupts from ppc_pending_interrupt_p7 |

The Hypervisor Virtualization Interrupt was introduced in PowerISA v3.0.
Critical Input, Watchdog Timer, and Fixed Interval Timer are only
defined for embedded CPUs. The Programmable Interval Timer is 40x-only.
The Event-Based Branch Facility was added in PowerISA v2.07.
