Update HDMI volatile registers list as DMA, Channel Selection registers,
vbit control registers are being reflected by hardware DP port
disconnection.
This update is required to fix no display and no sound issue observed
after reconnecting TAMA/SANWA DP cables.
Once DP cable is unplugged, DMA control registers are being reset by
hardware, however at second plugin, new dma control values does not
updated to the dma hardware registers since new register value and
cached values at the time of first plugin are same.

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.
