Add a device tree node for the IMG BXM-4-64 GPU present in the T-HEAD TH1520 SoC used by the Lichee Pi 4A board. This node enables support for the GPU using the drm/imagination driver. By adding this node, the kernel can recognize and initialize the GPU, providing graphics acceleration capabilities on the Lichee Pi 4A and other boards based on the TH1520 SoC.
