Subject: [PATCH 5/7] gpu: ipu-v3: Remove unused ipu_vdi_unsetup

From: "Dr. David Alan Gilbert" <linux@...blig.org>

ipu_vdi_unsetup() was added in 2016 by
commit 2d2ead453077 ("gpu: ipu-v3: Add Video Deinterlacer unit")
but has remained unused.

Remove it.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
