There happens to be an issue between how kernel handles qcom-smmuv2 and how the hypervisor would like it to be handled. That results in the platform hanging completely after the SMMUs are probed.
Hence, disable the SMMU nodes temporarily, until the issue is rectified. This has been overlooked by me in the initial porting stage, as my defconfig has SMMU disabled.
