Subject: [PATCH 1/2] ACPI: extlog: Trace CPER Non-standard Section Body

In extlog_print(), trace "Non-standard Section Body" reported by firmware
to the OS via Common Platform Error Record (CPER) (UEFI v2.10 Appendix N
2.3) to add further debug information and so to make ELOG log
consistently with ghes_do_proc() (GHES).
