I did a bit of data mining to remind myself why it was exported. Back
in a01b3d766c (v2.6.26) gianfar_mii was using it. That then got merged
into fsl_pq_mdio.c and gianfar_mii was deleted. Then finally in commit
28d8ea2d568 (v3.2) the one instance of code that was using it got
removed. So, I think this should be OK (but for net-next, though).
