0ac023faa6 fsl_pq_mdio: Revive UCC MDIO support
commit 1577ecef76 ("netdev: Merge UCC
and gianfar MDIO bus drivers") introduced a regression so that UCC
MDIO buses no longer work.

This is because fsl_pq_mdio driver wrongly masks all non-TBI PHYs
for !fsl,gianfar-mdio buses, while it should do that only for
fsl,gianfar-tbi buses.

18f27383d9 fsl_pq_mdio: Use proper address translation
Currently the driver just read "reg" property for constructing MDIO
bus IDs, but this won't work when we'll start using "ranges = <>" in
the device tree, so this will pop up:

This patch fixes the issue by translating the "reg" property to a full
address, and thus avoids the duplicate names.

301968451d fsl_pq_mdio: Revive Gianfar TBI PHY support
commit 1577ecef76 ("netdev: Merge UCC
and gianfar MDIO bus drivers") broke the TSEC TBI PHY support: the
driver now refuses to probe TBI MDIO buses as it doesn't know about
"fsl,gianfar-tbi" compatible entry, and thus _probe() fails with
-ENODEV status.

Fix this by adding "fsl,gianfar-tbi" to the list of known Gianfar
MDIO buses.

1577ecef76 netdev: Merge UCC and gianfar MDIO bus drivers
The MDIO bus drivers for the UCC and gianfar ethernet controllers are
essentially the same.  There's no reason to duplicate that much code.
