[PATCH] net: dsa: mv88e6xxx: fix mdio bus name when using devicetree

[Sylvain Lemieux]

From: Liam Beguin <lbeg...@tycoint.com>

mv88e6xxx_mdio_register automatically generates mdio buses for each switch
discovered in the devicetree. When switch nodes are embedded in other nodes,
this can cause sysfs naming collisions since full_name may be truncated.

Only use devicetree node name instead of the full devicetree path
as the mdio bus name.
