The canonical location for the tracefs filesystem is at
/sys/kernel/tracing.

But, from Documentation/trace/ftrace.rst:

  Before 4.1, all ftrace tracing control files were within the debugfs
  file system, which is typically located at /sys/kernel/debug/tracing.
  For backward compatibility, when mounting the debugfs file system,
  the tracefs file system will be automatically mounted at:

  /sys/kernel/debug/tracing

Update the visl decoder driver documentation to use this tracefs path.

source.codeaurora.org is no longer accessible and so the reference links
in the documentation are not useful.  The content was mirrored over to
Code Linaro so lets update the references to point there instead.

The vs6624 camera sensor driver doesn't support DT and relies on
platform data. The last board files supplying platform data for that
device have been removed from the kernel in v4.17. The driver hasn't
been used since them. Drop it.

The sr030pc30 camera sensor driver doesn't support DT and relies on
platform data. No board file has ever provided platform data for that
device. The driver has thus never been used in the mainline kernel since
its introduction in v2.6.37. Drop it.

The noon010pc30 camera sensor driver doesn't support DT and relies on
platform data. The last board files supplying platform data for that
device have been removed from the kernel in v3.16. A device tree file
referencing the device has been added in v3.17, but without
corresponding DT bindings, and with DT support in the driver. The driver
thus hasn't been used since v316. Drop it.
