Add a new SoC-specific compatible ("thead,th1520-gpu") for the T-HEAD
TH1520 GPU, alongside the Imagination BXM family compatible
("img,img-bxm"). This documents the GPU integration on the T-HEAD
platform.
Also adjust clock name constraints to accommodate a second clock named
"sys" instead of "mem" for T-HEAD. This is achieved by changing the
order, and making the 'sys' appear before 'mem'.
Provide example of the new GPU node.
