arm64: dts: imx952: Describe Mali G310 GPU
Support Mali G310 GPU on i.MX952 board. Describe this GPU in the DT. Include dummy GPU voltage regulator and OPP tables. A hardware GPU auto clock‑gating mechanism has been introduced, enabling GPUMIX to automatically manage the GPU clock. This improves overall response time.
