iommu: Add missing dependencies



parisc:allmodconfig, xtensa:allmodconfig, and possibly others generate
the following Kconfig warning.

warning: (IPMMU_VMSA && ARM_SMMU && ARM_SMMU_V3 && QCOM_IOMMU) selects
IOMMU_IO_PGTABLE_LPAE which has unmet direct dependencies (IOMMU_SUPPORT &&
HAS_DMA && (ARM || ARM64 || COMPILE_TEST && !GENERIC_ATOMIC64))

IOMMU_IO_PGTABLE_LPAE depends on (COMPILE_TEST && !GENERIC_ATOMIC64),
so any configuration option selecting it needs to have the same dependencies.
