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

This reverts commit 40a904b.

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

	Fixes: 060ad66 ("dpaa_eth: change DMA device")

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

git tag --contains 060ad66
v5.5

which then means it should have not been backported to linux-5.4.y,
where things _were_ working and now they're not.
