iommu/amd: Unexport get_dev_data()
This function is internal to the AMD IOMMU driver and only exported
because the amd_iommu_v2 modules calls it. But the reason it is called
from there could better be handled by amd_iommu_is_attach_deferred().
So unexport get_dev_data() and use amd_iommu_is_attach_deferred()
instead.
