Sascha Bischoff 3f5aeaf8d9 Documentation: KVM: Clarify that PMU_V3_IRQ IntID requirements for GICv5 
When running a GICv5-based guest, the PMU must use PPI 23. This,
however, must be communicated via the
KVM_ARM_VCPU_PMU_V3_CTRL->KVM_ARM_VCPU_PMU_V3_IRQ ioctl as a full
GICv5-style Interrupt ID. That is, 0x20000017. Optionally, the whole
ioctl can be skipped for GICv5.

This was previously not clearly documented, so bump the documentation
accordingly.

Fixes: 7c31c06e2d ("KVM: arm64: gic-v5: Mandate architected PPI for PMU emulation on GICv5")
