UEFI spec allows for non-standard section in 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 with
any section type that the kernel knows how to parse, trace event
is not generated for such section. And thus user is not able to know
happening of such hardware error, including error record of
non-standard section.

This commit generates a trace event which contains raw error data
for unrecognized CPER section.
