ACPI 6.5 added six new error types for CXL. See chapter 18
table 18.30.
Add strings for the new types so that Linux will list them in the
/sys/kernel/debug/apei/einj/available_error_types file.
It seems no other changes are needed. Linux already accepts
the CXL codes (on a BIOS that advertises them).
