From: Li Liu <john.liuli at huawei.com> Add a new register offset VIRTIO_MMIO_ISRMEM which help to estblish a shared memory region between virtio-mmio driver and qemu with two purposes: 1.Guest virtio-mmio driver can get the interrupt reason. 2.Check irqfd enabled or not to register different irq handler.
