This change was suggested by Laurent Pinchart and was introduced in v3. Quoting
Laurent:
"The idea is that enabling support for ADV7511 audio in the kernel isn't coupled
with whether the system includes audio support. It would be confusing, and would
also waste resources, to create a Linux sound device when no sound channel is
routed on the board."

Should I revert this?
