[netdrvr] gianfar: Determine TBIPA value dynamically
TBIPA needs to be set to a value (on connected MDIO buses) that doesn't conflict with PHYs on the bus. By hardcoding it to 0x1f, we were preventing boards with PHYs at 0x1f from working properly. Instead, scan the bus when it comes up, and find an address that doesn't have a PHY on it. The TBI PHY configuration code then trusts that the value in TBIPA is either safe, or doesn't matter (ie - it's not an active bus with other PHYs).
