target/ppc: remove unused interrupts from p8_deliver_interrupt
Remove the following unused interrupts from the POWER8 interrupt processing method: - PPC_INTERRUPT_RESET: only raised for 6xx, 7xx, 970 and POWER5p; - Debug Interrupt: removed in Power ISA v2.07; - Hypervisor Virtualization: introduced in Power ISA v3.0; - Critical Input, Watchdog Timer, and Fixed Interval Timer: only defined for embedded CPUs; - Critical Doorbell: processor does not implement the "Embedded.Processor Control" category; - Programmable Interval Timer: 40x-only; - PPC_INTERRUPT_THERM: only raised for 970 and POWER5p; Signed-off-by: Matheus Ferst <matheus.ferst@eldorado.org.br> Reviewed-by: Fabiano Rosas <farosas@linux.ibm.com> Message-Id: <20221011204829.1641124-16-matheus.ferst@eldorado.org.br> Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com>
