arm64: dts: imx952: Describe Mali G310 GPU

Browse Source 
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.
