media: fsl-viu: remove deprecated driver

The fsl-viu driver does not use the vb2 framework for streaming
video, instead it uses the old vb1 framework and nobody stepped in to
convert this driver to vb2.

The hardware is very old, so the decision was made to remove it
altogether since we want to get rid of the old vb1 framework.

-This is one of the few drivers still not using the vb2
-framework, so this driver is now deprecated with the intent of
-removing it altogether by the beginning of 2023.
-
-In order to keep this driver it has to be converted to vb2.
-If someone is interested in doing this work, then contact the
-linux-media mailinglist (https://linuxtv.org/lists.php).
