Remove the following unused interrupts from the POWER7 interrupt
processing method:
- PPC_INTERRUPT_RESET: only raised for 6xx, 7xx, 970 and POWER5p;
- Hypervisor Virtualization: introduced in Power ISA v3.0;
- Hypervisor Doorbell and Event-Based Branch: introduced in
Power ISA v2.07;
- Critical Input, Watchdog Timer, and Fixed Interval Timer: only defined
for embedded CPUs;
- Doorbell and Critical Doorbell Interrupt: processor does not implement
the Embedded.Processor Control category;
- Programmable Interval Timer: 40x-only;
- PPC_INTERRUPT_THERM: only raised for 970 and POWER5p;
