[PATCH] ARM: rdu-common: restart machine after fixing i210 device ID

[Lucas Stach]

For the iNVM change to take effect we need to reset the i210 adapter.
As this is not really possible in isolation in Barebox, we just go
through a full machine reset cycle. As this should only happen once
during the lifetime of each device there is no need for a more
elaborate solution.
