net/ncsi: NCSI response packet handler
The NCSI response packets are sent to MC (Management Controller) from the remote end. They are responses of NCSI command packets for multiple purposes: completion status of NCSI command packets, return NCSI channel's capability or configuration etc. This defines struct to represent NCSI response packets and introduces function ncsi_rcv_rsp() which will be used to receive NCSI response packets and parse them.
