[OE-core] Cross referencing git commit SHA info in commit logs

[Khem Raj]

Hello,

I have seen some commit logs referring to poky commits but are applied
to OE-Core and there might be vice versa case too. In general I don't
see an issue
when there is a commit SHA id in log message but please add the
project info to it unless so someone can go and look for it in
particular repo

eg, poky/<id> OE-Core/<id> meta-oe/<id>  oe.dev/<id> would make it a bit better

Thanks
