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.

cdx: controller: Drop useless probe success message
Drivers should be silent on probe success, unless they print some useful
information. Printing "hey I probed" is not useful and kernel already
gives mechanism to investigate that (e.g. sysfs, tracing, initcall
debug).
