Revert "arm: Remove d2net_v2 defconfig file"

Upon further review when populating README.scrapyard, d2net_v2 is a
variant on net2big_v2 and not just an orphan config.  To help in the
future also add this to board/LaCie/net2big_v2/MAINTAINERS which needed
a little consolidation anyhow.

This reverts commit 1363740e7948a8e4bee8d5adcdf0f63f7782879d.
