[PATCH] ACPI: APEI: EINJ: Add CXL error types

[Tony Luck <tony.luck@intel.com>]

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).
