In order to enforce per-SoC register rules, add per-compatible restrictions. For example, V3D 3.3 (used in brcm,7268-v3d) has a cache controller (GCA), which is not present in other V3D generations. Declaring these differences helps ensure the DTB accurately reflect the hardware design. The example was using an incorrect order for the register names. This commit corrects that by enforcing the order established in the register items description.
