We had this discussion already.  In my tests, I had to locate this entry
before these entries:

	{
		.compatible	= "fsl,dpaa"
	},
	{
		.compatible	= "fsl,srio",
	},

otherwise, the mdio-mux code would not prepare the mdio mus in time, and
there would be initialization failures.  Now maybe this goes away with
-EPROBE_DEFER, or maybe it doesn't.  But until we push the DPAA drivers
upstream, we won't know.
