Power Supply Cold Redundancy

[Yang, Cheng C]

Hi Brad & James,

     I am going to upstream an Intel specific feature called Power 
Supply Cold Redundancy which is to keep one PSU in standby mode when 
there are two PSU on the system.

You can get more information about this feature in design doc 
https://gerrit.openbmc-project.xyz/c/openbmc/docs/+/27637

My question is which repo should I push the code, is there any exist 
repo maintain all PSU related features? If not can you help to create a 
repo for this?


Thank you very much!
