fw-update: Firmware discovery of MCTP endpoints
Tested:
a) Verified MCTP endpoints are discovered by PLDM and fetching the firmware
inventory commands.
b) PLDM firmware update successful after uploading the package, which depends
on the firmware inventory commands.
c) Verified MCTP endpoints are discovered irrespective of the startup order
with the MCTP control application.
