board/BuR/common: Introduce Network Console and common environment for it

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.
