[U-Boot] [PATCHv2] socfpga: initialize designware ethernet

[Pavel Machek]

Enable initialization fo designware ethernet controller. With this
patch, ethernet works in my configuration, provided I set ethernet
address in the environment.

Changes from v1: moved ethernet initialization to arch/arm, as
suggested by Marek.
