iommu/amd: Do sanity check for address translation and irq remap of old dev table entry
Firstly split the dev table entry copy into address translation part
and irq remapping part. Because these two parts could be enabled
independently.
Secondly do sanity check for address translation and irq remap of old
dev table entry separately.
