PLDM Platform specification defines 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.
This patch test PLDM platform Init implementation
using commands
1. PLDM_PLATFORM_EVENT_MESSAGE
2. PLDM_GET_PDR
