Tyler Baicar 0fc300f414 efi: print unrecognized CPER section 
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
one of the section types that the kernel knows how to parse, the
section is skipped. Therefore, user is not able to see
such CPER data, for instance, error record of non-standard section.

This change prints out the raw data in hex in the dmesg buffer so
that non-standard sections are reported to the user. Non-standard
section type errors should be reported to the user because these
can include errors which are vendor specific. The data length is
taken from Error Data length field of Generic Error Data Entry.

The following is a sample output from dmesg:
 Hardware error from APEI Generic Hardware Error Source: 2
 It has been corrected by h/w and requires no further action
 event severity: corrected
  time: precise 2017-03-15 20:37:35
  Error 0, type: corrected

...

The raw data from the error can then be decoded using vendor
specific tools.
