net/davinci_emac: fix failing PHY connect attempts

Browse Source 
PHY connect attempts fail if no PHY id is specified in the emac platform
data and another mdio bus has been registered before 'davinci_mdio' bus. In
this case when configuring the interface, there will be an attempt to
connect to already attached PHY on the previously registered mdio bus:

net eth1: PHY already attached
net eth1: could not connect to phy smsc911x-0:01
IP-Config: Failed to open eth1
IP-Config: Device `eth1' not found

Fix this by modifying match_first_device() to match first PHY device
on 'davinci_mdio' bus.
