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.
