Jian Jun Chen e3f4e34c01 dm: virtio: implement vhost_vq_register_eventfd ...

There are 2 eventfds for one virtqueue, one is for kick and the other
is for notify. eventfd used for kick is associated with a PIO/MMIO
region. eventfd used for notify is associated with a MSIx/INTx. The
eventfd pair is registered to VHM thru VHM char dev.

VHM irqfd currently only support MSIx. If INTx is used, vhost proxy
uses mevent to poll the call fd from vhost then inject interrupt to
guest.
