PLDM is designed to be an interface and data model that provides efficient
access to low-level platform inventory, monitoring, control, event, and
data/parameters transfer functions. For example, temperature, voltage, or
fan sensors can have a PLDM representation that can be used to monitor or
control the platform using a set of PLDM messages. PLDM over MCTP binding
defines the format of PLDM over MCTP messages.

This patch set covers these following steps:
- initialize MCTP binding over LPC Bus interface.
- define PLDM responder and PLDM control and discovery requests.
- define PLDM requester and define the functions and data structures used
for discovering, describing, initializing, and accessing sensors and
effecters within the management controllers and management devices of a
platform management subsystem using PLDM messaging. 
- encode and decode APIs for in-band readFile and writeFile commands.

To enable the new PLDM features, add CONFIG_PLDM as a parameter:
  make .... CONFIG_PLDM=1

This patch set should be applied on top of this previous set:
Import external libraries for MCTP/PLDM protocols.

Changelog[v3]
 - Rebase to latest upstream.
 - patch1 : - Current IPMI testcase broken.
 - patch9 : - Consider the dest_id in pldm_send().
 - patch10: - Add a comment.
 - patch15: - Update find_lid_by_attr_name().
 - patch16: - Copy fsdata.length in the returned structure.
 - patch20: - Cleanup write_file_req().

Changelog[v2]
 - Rebase to latest upstream.
 - patch3 : - Patch is now correctly built.
 - patch9 : - Update number of retries.
 - patch10: - Update traces.
 - patch11: - Add new parameter (no_timeout) for the api:
              set_state_effecter_states_req().
 - patch12: - Call set_state_effecter_states_req() with the new parameter.
 - patch13: - Call set_state_effecter_states_req() with the new parameter.
 - patch14: - Update traces.
 - patch15: - Change the signature of pldm_bios_get_lids_id().
 - patch16: - Add new PLDM FRU requests.
