When initializing the test reset any media links and set a know
resolutions. This is needed to put the device under test into known
state and not have the v4l2 device tests depend on that no one have
touched the device before the test is executed.

The resolution is picked purely at random and could possibly be moved to
each test case if there is a need for different resolutions for a
specific one.
