CCGx controller used on NVIDIA GPU card has two separate display altmode for two DP pin assignments. UCSI specification doesn't prohibits using separate display altmode. Current UCSI Type-C framework expects only one display altmode for all DP pin assignment. This patch squashes two separate display altmode into single altmode to support controllers with separate display altmode. We first read all the alternate modes of connector and then run through it to know if there are separate display altmodes. If so, it prepares a new port altmode set after squashing two or more separate altmodes into one.

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.
