hw/ast-bmc: Initialize ast lpc mctp binding

The Management Component Transport Protocol (MCTP) defines a communication
model intended to facilitate communication.

This patch initialize MCTP binding over LPC Bus interface.

Several steps must be performed:
- Initialize the MCTP core (mctp_init()).
- Initialize a hardware binding as AST LPC mode host (mctp_astlpc_init()).
- Register the hardware binding with the core (mctp_register_bus()), using
a predefined EID (Host default is 9).

To transmit a MCTP message, mctp_message_tx() is used.
To receive a MCTP message, a callback need to be provided and registered
through mctp_set_rx_all().

For the transfer of MCTP messages, two basics components are used:
- A window of the LPC FW address space, where reads and writes are
forwarded to BMC memory.
- An interrupt mechanism using the KCS interface.

hw/ast-bmc/ast-mctp.c is compilated if the compiler flag CONFIG_PLDM is
set.
