iommu/amd: Initialize device table after dma_ops
commit f528d980c17b8714aedc918ba86e058af914d66b upstream.
When dma_ops are initialized the unity mappings are
created. The init_device_table_dma() function makes sure DMA
from all devices is blocked by default. This opens a short
window in time where DMA to unity mapped regions is blocked
by the IOMMU. Make sure this does not happen by initializing
the device table after dma_ops.
