ras: acpi / apei: generate trace event for unrecognized CPER section
The UEFI spec includes non-standard section type support in the Common Platform Error Record. This is defined in section N.2.3 of UEFI version 2.5. Currently if the CPER section's type (UUID) does not match any section type that the kernel knows how to parse, a trace event is not generated. Generate a trace event which contains the raw error data for non-standard section type error records.
