Ben Wei 6f671045b6 net/ncsi: add response handlers for PLDM over NC-SI
This patch adds handlers for PLDM over NC-SI command response.

This enables NC-SI driver recognizes the packet type so the responses
don't get dropped as unknown packet type.

PLDM over NC-SI are not handled in kernel driver for now, but can be
passed back to user space via Netlink for further handling.

Gavin Shan 7a82ecf4cf net/ncsi: NCSI AEN packet handler
This introduces NCSI AEN packet handlers that result in (A) the
currently active channel is reconfigured; (B) Currently active
channel is deconfigured and disabled, another channel is chosen
as active one and configured. Case (B) won't happen if hardware
arbitration has been enabled, the channel that was in active
state is suspended simply.

Gavin Shan 138635cc27 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.

NCSI channel etc.

This defines struct to represent NCSI command packets and introduces
function ncsi_xmit_cmd(), which will be used to transmit NCSI command
packet according to the request. The request is represented by struct
ncsi_cmd_arg.
