ppc: Don't use CPUPPCState::irq_input_state with modern Book3s CPU models
The power7_set_irq() and power9_set_irq() functions set this but it is
never used actually. Modern Book3s compatible CPUs are only supported
by the pnv and spapr machines. They have an interrupt controller, XICS
for POWER7/8 and XIVE for POWER9, whose models don't require to track
IRQ input states at the CPU level.
Drop these lines to avoid confusion.
