Add new subtest to video_device_test to cover the VIDIOC_G_PRIORITY and VIDIOC_S_PRIORITY ioctl calls. This test tries to set the priority associated with the file descriptior via ioctl VIDIOC_S_PRIORITY command from V4L2 API. After that, the test tries to get the new priority via VIDIOC_G_PRIORITY ioctl command and compares the result with the v4l2_priority it set before. At the end, the test restores the old priority. This test will increase the code coverage for video_device_test, so I think it might be useful. Additionally, this patch will refactor the video_device_test a little bit, according to the new functionality.

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.
