[PATCH v4 01/20] drm/tyr: remove unused device from platform data

[Deborah Brouwer]

TyrPlatformDriverData stores an ARef to the DRM device to keep it alive,
but after switching to Registration::new_foreign_owned(), the registration
owns the device, so the extra reference is no longer needed.

Remove the device field and return an empty TyrPlatformDriverData instead.
