[PATCHv3 1/3] net/lwip: add lwip-external submodule

This commit adds the lwip library as a git submodule. I think
there has to be advantages to compile lwip inside U-boot,
i.e. use the same compiler and flags as the main code.
One of them is LTO and the other is to enable additional debug
options for network protocol during development. Also we can
copy lwip library code inside U-boot, but for now I don't want
to send all lwip code to the mailing list. So it's git submodule.
