The current (mildly evil) fsl_pq_mdio code uses an undocumented shadow of
the TBIPA register on LS1021A, which happens to be read-only.
Changing TBI PHY address therefore does not work on LS1021A.
The real (and documented) address of the TBIPA registere lies in the eTSEC
block and not in MDIO/MII, which is read/write, so using that fixes
the problem.
