Commit 54ce1927 ("cxl/cper: Fix errant CPER prints for CXL events")
moved the CXL CPER section defines to include/linux/cper.h from ghes.c

When the latest cxl/cper series was reworked those defines were kept in
ghes.c by accident.  Thus they were duplicated.

Delete the duplicate defines keeping them in the header to be shared
between efi and apei.
