drm/vc4: hdmi: Stop checking for enabled output in audio 
The current HDMI driver, in vc4_hdmi_audio_can_stream() checks whether
the display output is enabled.

This has been there in one form or the other since the introduction of
the audio support in the VC4 HDMI driver in commit bb7d785688
("drm/vc4: Add HDMI audio support"), but no justification for this check
is in the commit message, or in the discussions around the patches.

One can only assume this was done to prevent a user from playing audio
on the ALSA soundcard when the monitor doesn't support it.

However, this is causing some issues. Indeed, Kodi, for example, was
hitting some errors if it was streaming audio during a modeset. With the
theory above, it does make sense, but the display and audio threads are
typically completely different processes with no opportunity to
synchronise which makes it hard to workaround.

Removing that check also doesn't seem to cause any trouble, so let's
just remove it.

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.
