Rodrigo Vivi 381f957044 drm/i915: Enable voltage swing before enabling DDI_BUF_CTL.
Sequences for DisplayPort asks us to
" Configure voltage swing and related IO settings.
Refer to DDI Buffer section."

before "Configure and enable DDI_BUF_CTL"

On BXT and CNL this means to execute the ddi vswing sequences.

At this point these sequences calls are getting duplicated for DP
because they are all called from DP link trainning sequences.

However this patch is not yet removing it before a futher discussion
since spec also allows that during link training without disabling
anything:

"
Notes
Changing voltage swing during link training:
Change the swing setting following the DDI Buffer section.
The port does not need to be disabled.

README

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.
