V3D 7.1 exposes a new register block, called V3D_SMS. As BCM2712 has a
V3D 7.1 core, add a new register item to the list. Similar to the GCA
and bridge register, SMS is optional and should only be added for V3D
7.1 variants.
In order to enforce per-SoC register rules, add per-compatible
restrictions. The restrictions will assure that GCA will only be added
in BCM7268 (V3D 3.3) and SMS will only be added in BCM2712 (V3D 7.1).
