net: au1000_eth: fix PHY detection
Commit 7f854420fbfe9d49afe2ffb1df052cfe8e215541
("phy: Add API for {un}registering an mdio device to a bus.")
broke PHY detection on this driver with a copy-paste bug:
The code is looking 32 times for a PHY at address 0.
Fixes ethernet on AMD DB1100/DB1500/DB1550 boards which have
their (autodetected) PHYs at address 31.
