[U-Boot] [PATCHv3] 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.

Signed-off-by: Pavel Machek <pavel at denx.de>

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

Changes from v2: use right function name after moving to
arch/arm. Thanks to Marek.

Patch hand-edited so that it can be applied after the "timer counts
down" fix.
