xics-kvm: enable irqfd for MSI
This enables IRQFD support for sPAPR. The feature decreases the latency
of interrupt handling.
To enable IRQFD for MSI, this sets kvm_gsi_direct_mapping to true which
enables direct MSI mapping.
To enable IRQFD for LSI (level triggered INTx interrupts), a PCI host bus
callback is required. The patch for that is coming next.
