Revert "dpaa_eth: fix usage as DSA master, try 3"

This reverts commit b145710b which is
commit 5d14c304bfc14b4fd052dc83d5224376b48f52f0 upstream.

The patch is not wrong, but the Fixes: tag is. It should have been:

	Fixes: 060ad66f9795 ("dpaa_eth: change DMA device")

which means that it's fixing a commit which was introduced in:

git describe --tags 060ad66f97954
v5.4-rc3-783-g060ad66f9795

which then means it should have not been backported to linux-4.19.y,
where things _were_ working and now they're not.
