3.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jason Gunthorpe <[email protected]>

Commit cc9d4598 'net: mv643xx_eth: use of_phy_connect if phy_node
present' made the call to phy_scan optional, if the DT has a link to
the phy node.

However phy_scan has the side effect of calling phy_addr_set, which
writes the phy MDIO address to the ethernet controller. If phy_addr_set
is not called, and the bootloader has not set the correct address then
the driver will fail to function.

Tested on Kirkwood.
