Add the device tree node for the T-HEAD TH1520 GPU power sequencer (gpu_pwrseq) to the th1520.dtsi file. This node instantiates the thead,th1520-gpu-pwrseq driver, which is responsible for managing the GPU's power-on/off sequence. The node specifies the gpu-clkgen reset, which is one of the resources controlled by this sequencer.
