Lukas Wunner 6fb9367a15 efi/cper: Fix endianness of PCIe class code
The CPER parser assumes that the class code is big endian, but at least
on this edk2-derived Intel Purley platform it's little endian:

    efi: EFI v2.50 by EDK II BIOS ID:PLYDCRB1.86B.0119.R05.1701181843
    DMI: Intel Corporation PURLEY/PURLEY, BIOS PLYDCRB1.86B.0119.R05.1701181843 01/18/2017

    {1}[Hardware Error]:   device_id: 0000:5d:00.0
    {1}[Hardware Error]:   slot: 0
    {1}[Hardware Error]:   secondary_bus: 0x5e
    {1}[Hardware Error]:   vendor_id: 0x8086, device_id: 0x2030
    {1}[Hardware Error]:   class_code: 000406
                                       ^^^^^^ (should be 060400)

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
