[PATCH] powerpc: Fix crash introduced with commit 5657933dbb6e

[Larry Finger]

Code inserted during the git merges before kernel 4.11-rc1 caused an
early panic quickly followed by a complete shutdown. The traceback was
not displayed long enough to read or photograph.

The problem was bisected to commit 5657933dbb6e ("treewide: Move dma_ops
from struct dev_archdata into struct device"). The problem was a missing
copy of critical information from struct dev_archdata into struct device,
leading to the dereference of a null pointer.

Fixes: commit 5657933dbb6e ("treewide: Move dma_ops from struct dev_archdata into struct device")
