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. Add fixed clock gpu_mem_clk, as the MEM clock on the T-HEAD SoC can't be controlled programatically.
