net: amd: mvme147: Fix probe banner message

[ Upstream commit 82c5b53140faf89c31ea2b3a0985a2f291694169 ]

Currently this driver prints this line with what looks like
a rogue format specifier when the device is probed:
[    2.840000] eth%d: MVME147 at 0xfffe1800, irq 12, Hardware Address xx:xx:xx:xx:xx:xx

Change the printk() for netdev_info() and move it after the
registration has completed so it prints out the name of the
interface properly.
