cper.c contains code to decode and print "Common Platform Error Records".
Originally added under drivers/acpi/apei because the only user was in that
same directory - but now we have another consumer, and we shouldn't have
to force CONFIG_ACPI_APEI get access to this code.

Since CPER is defined in the UEFI specification - the logical home for
this code is under drivers/firmware/efi/
