rust: drm: return ParentDevice from Device AsRef

Browse source

Change AsRef for drm::Device to return &T::ParentDevice<device::Normal>
instead of &device::Device, and restrict it to the Normal context.
Device<T, Registered> still gets this through Deref coercion.

This provides access to the typed parent bus device rather than the raw
base device.
