Subject: [PATCH] checkpatch: whitelist Originally-by: signature

Oftentimes [1], the contributor would like to honor or give credits [2]
to somebody's original ideas in the submission/reviewing process. While
"Co-developed-by:" and "Suggested-by:" (currently whitelisted) could be
employed for this purpose, they are not ideal.

Below matrix attempts portraying/quantifying the subtle differences
between these signatures (subjective/oversimplified):

Helper signature    Contribution "ownership"
None                100% Author
Suggested-by: X     80% Author / 20% "X"
Co-developed-by: X  50% Author / 50% "X"
Originally-by: X    20% Author / 80% "X"
