[DO NOT MERGE] Reorganize our overlays based on manufacturer

* If we strive to organize our feature dependent config overlays,
  duplicates (overlay for d2 and jf may be the same) are inevitable.
* Restructure based on manufacturer with common directories within it
  for a cleaner top-down file structure.
