Subject: [PATCH] net: mv643xx_eth: fix DT port device name

Device tree support added to Marvell MV643xx ethernet driver registers
port devices from port device nodes found on the corresponding controller
node. The current port device name will cause the second controller to
fail on registration because of two identical device names. This fixes
the issue by taking the device node's name also as port device name.
