docs: ABI: iommu: remove duplicated definition for sysfs-kernel-iommu_groups 



./scripts/get_abi.pl is reporting a duplicated definition for
/sys/kernel/iommu_groups/reserved_regions, both at the same
file:

	Warning: /sys/kernel/iommu_groups/reserved_regions is defined 2 times:  Documentation/ABI/testing/sysfs-kernel-iommu_groups:15  Documentation/ABI/testing/sysfs-kernel-iommu_groups:27

Fix it by merging those into an unified entry.
