[PATCH v3 4/8] dt-bindings: gpu: Add TH1520 GPU compatible to Imagination bindings

[Michal Wilczynski]

Update the img,powervr-rogue.yaml device tree bindings to include the
T-HEAD TH1520 SoC's specific GPU compatible string.

The thead,th1520-gpu compatible, along with its full chain
img,img-bxm-4-64, and img,img-rogue, is added to the
list of recognized GPU types. This allows the Imagination DRM driver
to correctly bind to the GPU node defined in the TH1520 device tree.

The power-domains property requirement for img,img-bxm-4-64 is also
ensured by adding it to the relevant allOf condition.
