Analog video signals on VGA or DVI-A (analog part of DVI-I) don't support audio, so avoid calling any audio related functions on analog signals. Stereo sync was not set up for analog signals in the legacy display code either, so there is no loss of functionality if we omit it from DC for now. Also add a dc_is_rgb_signal similar to other dc_is_*_signal. v2: Added comment to clarify what we mean by RGB in this context.

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.
