Could you please rebase you patch on top of
https://patchwork.freedesktop.org/series/119804/
That patchset removes the need for per-SoC, per-SSPP sblk structures.
I'm mostly sure that sdm670 has scaler version 1.3 (the same as sdm845),
but you can verify this by reading the register 0x0ae05a00.

We were duplicating the data for different platforms, even if they
looked similar, it was not obvious what is the actual level of
similarity. Nevertheless, for the sdm670 / sdm845 pair I think this
looks good. Especially since we do not expect other DPU 4.x platforms.
