KVM: Add devid in kvm_kernel_irq_routing_entry
Enhance kvm_kernel_irq_routing_entry to transport the device id field, devid. A new flags field makes possible to indicate the devid is valid. Those additions are used for ARM GICv3 ITS MSI injection. The original struct msi_msg msi field is replaced by a new custom structure that embeds the new fields.
