Add support to handle control virtqueue configurations per virtio specification. The control virtqueue is implemented in software and no hardware offloading is involved. Control VQ configuration need task context, therefore all configurations are handled in a workqueue created for the purpose. Modifications are made to the memory registration code to allow for saving a copy of itolb to be used by the control VQ to access the vring. The max number of data virtqueus supported by the driver has been updated to 2 since multiqueue is not supported at this stage and we need to ensure consistency of VQ indices mapping to either data or control VQ.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
