Add build instructions kgpe-d16

[arhabd]

pretty much just follow the readme instructions

@arhabd I think we are going in the wrong direction here. I thin no board specific instructions at all should be in wiki and the general instructions point back to heads repo's README.

This is duplicating maintenance with no good reason.

@arhabd can you remove duplication instead?

Removed the duplicate text and only keept the kgpe-d16 specific make command and the git clone command as its not stated in the readme to clone the repo. Note the readme points to the wiki for building but the wiki points to the readme for latest instructions that might be confusing?
