Subject: [PATCH v4 0/2] Enable smmu support on sdm845

This series enables apps-smmu, the "arm,mmu-500" instance
on sdm845.
Series tested on SDM845 MTP device with related smmu patch series [1],
and necessary config change, besides one hack to keep LDO14 in LPM mode
to boot things up (see the commit in the test branch).
The tested branch is available at [2].

Changes since v3:
 - Refined the dt binding documentation more to align with
   Rob's comments for qcom,smmu-v2 binding documentation [3]
   on SoC specific compatibles and state things similar
   to qcom,smmu-v2 [4].

Changes since v2:
 - Dropped patch for gpu-smmu [5] as the same has been pushed by
   Jordan [6] after incorporating the dt binding update.
 - Updated binding doc to include valid value for '<soc>'
   in "qcom,<soc>-smmu-500" compatible string.

Changes since v1:
 - Addressed Rob's review comments by adding a SoC specific compatible.
   Have added a new dt-bindings patch for this.
 - Updated node name to 'iommu'.
 - Addressed Doug's review comment about removing status property from
   smmu's nodes, as smmu is either present on the soc or not. Enabling
   it is not a board-level decision.
