[Skiboot] [PATCH 03/19] core/pldm: PLDM over MCTP Binding

[Christophe Lombard]

Enable the mctp binding over LPC bus interface and new wrappers to send
and receive PLDM messages over the mctp library.

PLDM is supported as a message type over MCTP. PLDM over MCTP binding
defines the format of PLDM over MCTP messages.

An MCTP Endpoint is the terminus for MCTP communication. A physical device
that supports MCTP may provide one or more MCTP Endpoints. Endpoints are
addressed using a logical address called the Endpoint ID, or EID. EIDs in
MCTP are analogous to IP Addresses in Internet Protocol networking.

The BMC EID default is 8.

First byte of the PLDM over MCTP Message Fields identifies the MCTP
message as carrying a PLDM message:
Message Type (7 bits)  PLDM = 0x01 (000_0001b).
