[U-Boot] [PATCH 12/21] board/BuR/common: Introduce Network Console and common environment for it

[Hannes Petermaier <oe5hpm@oevsv.at>]

It is often necessary to "break in" into boards bootloader commandline if
something fails or even for development purposes some parameters have to be
changed.

So we enable u-boot's CONFIG_NETCONSOLE feature.
We also modify Networksettings to apply with this new use-case.
