Nitin Kumbhar 8472163ba0 drivers: nv virtio poc console driver ...

Add a back-end char driver to implement a virtio console driver which
handles a part of virtio mmio protocol to send and receive data
from a peer VM. IVC queue and mempool are used for this communication.

Also, this driver adds blocking read, write and poll ops for an
user-space application.
