This is a single, straightforward patch that adds a device link between the DU (Display Unit) and the VSP (Video Signal Processor) to enforce correct suspend/resume ordering on Renesas RZ/G2L SoCs. The VSP must be suspended after and resumed before the DU, and a `DL_FLAG_STATELESS` device link achieves this.

The patch is a direct port of the same fix already present in the R-Car DU driver (`rcar_du_vsp.c:494`), as credited in the commit message. The implementation is correct and follows the established pattern exactly.

**Verdict: Patch looks good. No issues found.**
