I need to bring-up this page before merging, even if a small stub :/

I'm moving the ADRV9026 folder to solutions/reference-designs, and renamed the folder to eval-adrv902x because it includes the ADRV9029 as well, in this PR: #72
So maybe it would be better to apply this collection after my PR and after Jorge adds that stub for Linux.
