Upstream U-Boot for Linksys WRT1900ACS V2

[Brice GIBOUDEAU]

Yes I can provide a set of patchs and contribute to your version but for that there is two things we should tackle before.
- If you have a reference on how to contribute to OpenWrt the proper way please share it.
- I would like to enable other routers before pushing this to OpenWrt official repo. For now there is only one Board. I need contributors before to extend a bit what I have done that is very specific to one hardware release.
