cdx: Export Symbols for MCDI RPC and Initialization
The cdx_mcdi_init(), cdx_mcdi_process_cmd(), and cdx_mcdi_rpc() functions are
needed by the VersalNET EDAC module that interact with the MCDI (Management
Controller Direct Interface) framework. These functions facilitate
communication between different hardware components by enabling command
execution and status management.
