Jerome Forissier 1c41a7afaa net: lwip: build lwIP
Build the lwIP library when NET_LWIP is enabled. The following files
are adaptation layers written specially for U-Boot:

 lib/lwip/u-boot/arch/cc.h
 lib/lwip/u-boot/arch/sys_arch.h (empty)
 lib/lwip/u-boot/limits.h (empty)
 lib/lwip/u-boot/lwipopts.h

They were initially contributed by Maxim in a previous RFC patch series.

The lwIP stack needs to be added as a Git subtree with the following
command:

 $ git subtree add --squash --prefix lib/lwip/lwip \
   https://github.com/lwip-tcpip/lwip.git  STABLE-2_2_0_RELEASE
