cxl/trace: Add TRACE support for CXL media-error records
CXL devices may support the retrieval of a device poison list.
Add a new trace event that the CXL subsystem may use to log
the media-error records returned in the poison list.
Log each media-error record as a cxl_poison trace event of
type 'List'.
