drm/i915/bios: parse DDI ports also for CHV for HDMI DDC pin and DP AUX channel
While technically CHV isn't DDI, we do look at the VBT based DDI port info for HDMI DDC pin and DP AUX channel. (We call these "alternate", but they're really just something that aren't platform defaults.) In commit e4ab73a13291 ("drm/i915: Respect alternate_ddc_pin for all DDI ports") Ville writes, "IIRC there may be CHV system that might actually need this." I'm not sure why there couldn't be even more platforms that need this, but start conservative, and parse the info for CHV in addition to DDI.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
