Subject: [PATCH] iommu: arm-smmu-qcom: Add sdm630/msm8998 compatibles for qcom quirks

SDM630 and MSM8998 are among the SoCs that use Qualcomm's implementation
of SMMUv2 which has already proven to be problematic over the years. Add
their compatibles to the lookup list to prevent the platforms from being
shut down by the hypervisor at MMU probe.
