iommu/arm-smmu-qcom: Skip the TTBR1 quirk for MSM8998 and SDM630

Browse source 
Similarly to MSM8996 DragonBoard 820c, MSM8998 and SDM630 are equipped
with Adreno 5xx series, which doesn't have separate pagetables support
at the moment of writing.
Skip the TTBR1 quirk for these two SoCs as to get Adreno in a usable
state.
