Add a mechanism for DisplayID specific quirks, and add the first quirk to ignore DisplayID section checksum errors. It would be quite inconvenient to pass existing EDID quirks from drm_edid.c for DisplayID parsing. Not all places doing DisplayID iteration have the quirks readily available, and would have to pass it in all places. Simply add a separate array of DisplayID specific EDID quirks. We do end up checking it every time we iterate DisplayID blocks, but hopefully the number of quirks remains small. There are a few laptop models with DisplayID checksum failures, leading to higher refresh rates only present in the DisplayID blocks being ignored. Add a quirk for the panel in the machines.

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 reStructuredText 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.
