Subject: [PATCH] drm/tests: helpers: Make sure the device is bound

The device managed resources are freed when the device is detached, so
|
|
it has to be bound in the first place.
|
|
|
|
Let's create a fake driver that we will bind to our fake device to
|
|
benefit from the device managed cleanups in our tests.
