[PATCH v3 6/8] riscv: dts: thead: Add GPU power sequencer node

[Michal Wilczynski]

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.
