iommu/arm-smmu-v3: Remove the unused empty definition

arm_smmu_sva_remove_dev_pasid() has been removed since commit d38c28dbefee
("iommu/arm-smmu-v3: Put the SVA mmu notifier in the smmu_domain"), remain
the empty definition untouched in header file, which is used when
CONFIG_ARM_SMMU_V3_SVA is not set. So, let's remove the unused definition.
