target/ppc: remove unused interrupts from p9_deliver_interrupt
Remove the following unused interrupts from the POWER9 interrupt
processing method:
- PPC_INTERRUPT_RESET: only raised for 6xx, 7xx, 970 and POWER5p;
- Debug Interrupt: removed in Power ISA v2.07;
- Critical Input, Watchdog Timer, and Fixed Interval Timer: only defined
for embedded CPUs;
- Critical Doorbell Interrupt: removed in Power ISA v3.0;
- Programmable Interval Timer: 40x-only.
