[PATCH 1/3] EP93xx eth: allow passing of phy config via platform data

[Alexander Kurz <akurz@xxxxxxxx>]

Passing phy configuration to the ep93xx_eth driver was not supported yet
and will be added with this patch. When no pdata is passed, the probably
broken default of phy_addr = 0 will be used to maintain compatibility
with the previous implementation.
