[U-Boot] [PATCH v2 05/11] dm: net: Use existing Ethernet init for driver model

[Simon Glass]

At present even with driver model is used there is still much manual init
of related devices: PHY, environment and board init. Until these requirements
are dealt with in another way we need to keep them around.

Break out the init portion of the legacy eth_initialize() into a separate
function and call it from both the legacy and driver model eth_initialize()
functions.
