Changes since v2:
- Added missing opp level (both gpu and gmu)
- Corrected opp-level for highest gpu opp
- Added dma-coherent to gpu smmu

Note that in order for the GPU driver to probe, the last change
requires:
https://lore.kernel.org/linux-arm-msm/20230410185226.3240336-1-dmitry.baryshkov@linaro.org/

Changes since v1:
- Dropped gmu_pdc_seq region from &gmu, as it shouldn't have been used.
- Added missing compatible to &adreno_smmu.
- Dropped aoss_qmp clock in &gmu and &adreno_smmu.
