Add a driver for the AMD Versal NET DDR memory controller which supports
single bit error correction, double bit error detection and other system
errors from various IP subsystems (e.g., RPU, NOCs, HNICX, PL).
The driver listens for notifications from the NMC (Network management
controller) using RPMsg (Remote Processor Messaging).
The channel used for communicating to RPMsg is named "error_edac". Upon
receipt of a notification, the driver sends a RAS event trace.
