rust: drm: add AsRef<ParentDevice<Bound>> for Device<Registered>

Browse source

Implement AsRef<T::ParentDevice<Bound>> for Device<T, Registered>,
providing access to the bound parent bus device for registered DRM
devices.

Since a Device<T, Registered> guarantees that the parent bus device is
bound, the conversion to T::ParentDevice<Bound> is safe.
