T-HEAD Devicetrees for v6.17

Browse Source 
There are several additions for the T-Head TH1520 SoC:
 
  - Add PVT node for thermal sensor which works with the existing Moortec
    MR75203 driver.
  - Add "gpu-clkgen" reset property to the AON node which allows the power
    domain driver to detect the capability to power sequence the GPU.
 
 All of these patches have been tested in linux-next.
