powerpc/85xx: Don't scan for TBI PHY addresses on MPC8569E-MDS boards
Sometimes (e.g. when there are no UEMs attached to a board) fsl_pq_mdio_find_free() fails to find a spare address for a TBI PHY, this is because get_phy_id() returns bogus 0x0000ffff values (0xffffffff is expected), and therefore mdio bus probing fails with the following message: fsl-pq_mdio: probe of e0082120.mdio failed with error -16 And obviously ethernet doesn't work after this. This patch solves the problem by adding tbi-phy node into mdio node, so that we won't scan for spare addresses, we'll just use a fixed one.
