T-HEAD Devicetrees for 7.1, part 2

Browse Source 
Additional updates to T-Head device trees for v7.1:
 
  - Enable the display pipeline for the TH1520-based BeagleV Ahead board
    by adding the HDMI connector node, connecting it to the HDMI
    controller, and activating the DPU and HDMI nodes.
 
  - Add coefficients to the TH1520 PVT node as the values in the TH1520
    manual differ from the defaults in the driver.
