I asked an LLM to find is_rpmh && !dwc3_dma_coherent. It gave me:

- kodiak
- lemans
- monaco
- qdu1000
- sc7180
- sc8180x
- sc8280xp
- sdm670
- sdm845
- sdx75
- sm6350
- sm8150
- sm8250
- sm8350
- sm8450
- talos (fixed by this patch)
- qcom-sdx55
- qcom-sdx65

should we mark all of these coherent?
