rust: drm: Add Driver::ParentDevice associated type

Add a ParentDevice associated type to the Driver trait, allowing each
DRM driver to declare its parent bus device type (e.g.
auxiliary::Device, platform::Device).

Change UnregisteredDevice::new() to take &T::ParentDevice<Bound>,
ensuring at the type level that the DRM device's parent matches the
declared bus device type.
