[why] There is a change previously to disallow DM to set dp drive setings when stream is not present. The logic might not work well with DP PHY complaince scenario with a PHY test fixture attachment. We need to make the method allow DP link drive settings changes even without stream attached to it. [how] revert back to previous code in set drive setting function then add an empty link_resource structure, then assign link resource based on current link resource if link resource is allocated to the current pipe.

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.
