[U-Boot] [PATCH v2] board/BuR/kwb: use bootvx(...) (with bootline feature) instead go(...)

[Hannes Schmelzer]

Since we don't have for sure a valid IP-setup during
board_late_init(...) because it maybe allready stored in environment or
not, we cannot form a proper vxWorks bootline at this place.

So we move to the way, forming the bootline just before
executing/launching vxWorks. To do this we use the bootvx command
instead go.

We only have to form the "othbootargs" environment variable, the rest is
done pretty good by the "bootvx" commannd.

Changes in v2:
- form only othbootargs instead whole bootline within board-code
- depends now on Bin Mengs changes belong CMD_ELF
http://patchwork.ozlabs.org/patch/523289/
- adapt kwb_defconfig to the new Kconfig defaults
- use bootvx ... instead go ... to launch vxWorks kernel
