sidekiqz2: add support for new board
This patch adds support for the Sidekiq Z2 board from Epiq Solutions. It's a copy of Pluto with some adaptations inspired from M2k. Seems that M2k re-uses some Pluto parts. The same thing has been done for SidekiqZ2 to avoid some code duplication. The `msd` folder [which contains files that will be mounted on the user's system] contains only some stub files that may be modified later.
