[Why] USB-C DisplayPort Alt Mode with concurrent USB data needs lane count limitation to prevent incorrect 4-lane DP configuration when only 2 lanes are available due to hardware lane sharing between DP and USB3. [How] Query DMUB for Alt Mode status (is_dp_alt_disable, is_usb, is_dp4) in dcn32_link_encoder_get_max_link_cap() and cap DP to 2 lanes when USB is active on USB-C port. Added inline documentation explaining the USB-C lane sharing constraint.

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.
