Shuah Khan bc81c1c796 media: selftests: media_dev_allocator api test
Add a new test for Media Device Allocator API.

Media Device Allocator API to allows multiple drivers share a media device.
This API solves a very common use-case for media devices where one physical
device (an USB stick) provides both audio and video. When such media device
exposes a standard USB Audio class, a proprietary Video class, two or more
independent drivers will share a single physical USB bridge. In such cases,
it is necessary to coordinate access to the shared resource.

Using this API, drivers can allocate a media device with the shared struct
device as the key. Once the media device is allocated by a driver, other
drivers can get a reference to it. The media device is released when all
the references are released.

This test does a series of unbind/bind tests to make sure media device
is released correctly when it is no longer is use and when the last
driver releases the reference.
