Enable HDMI Colorspace for LSPCON based devices. Sending Colorimetry data for HDR using AVI infoframe. LSPCON firmware expects this and though SOC drives DP, for HDMI panel AVI infoframe is sent to the LSPCON device which transfers the same to HDMI sink. v2: Dropped state managed in drm core as per Jani Nikula's suggestion. v3: Aligned colorimetry handling for lspcon as per compute_avi_infoframes, as suggested by Ville. v4: Finally fixed this with Ville's help, re-phrased the commit header and description. v5: Register HDMI colorspace for lspcon and move this to intel_dp_add_properties as we can't create property at late_register.

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.
