Dmitry Baryshkov e72cd597c3 drm/connector: add CEC-related fields
As a preparation to adding HDMI CEC helper code, add CEC-related fields
to the struct drm_connector. The callbacks abstract CEC infrastructure
in order to support CEC adapters and CEC notifiers in a universal way.

CEC data is a void pointer as it allows us to make CEC data
helper-specific. For example, currently it will be either cec_notifier
or cec_adapter + drm_connector_hdmi_cec_funcs. Later cec-pin might store
platform callbacks here. DP CEC might need to store AUX pointer, etc.

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.
