Add APPS SMMU to SM6125 dtsi and use it in SDHCI/USB nodes.

Changes since v4:

- Use hexadecimal 0x0 for iommu mask;
- Add sm6125 to the dt-bindings list without clocks, now depending on:
  https://lore.kernel.org/linux-arm-kernel/20221222092355.74586-1-krzysztof.kozlowski@linaro.org/

v4: https://lore.kernel.org/linux-arm-msm/20221216215819.1164973-1-marijn.suijten@somainline.org/T/#u


Changes since v3:

- Drop driver patch in favour of using generic qcom,smmu-500 compatible;
- Add patches that use apps_smmu in USB and SDHCI nodes, reconfiguring
  their streamID which otherwise gets lost (from the bootloader) as soon
  as SMMU probes, breaking their functionality;
- Rebased on next-20221216 to solve dt-bindings conflict.
