Subject: [PATCH v2 00/18] media: mtk-vcodec: venc: support for MT8183 and v4l2-compliance fixes

This is the second revision of the series adding support for the MT8183 encoder
(patches 1-9). It also fixes 9 v4l2-compliance failures (patches 10-18). Of note
is patch 10 which reverts a previous patch that seems to have been merged by
mistake (see https://lore.kernel.org/linux-media/CAPBb6MWuhJGq_etJN4WX0NOBXK0cA7rxVCMx70xCg7Uzmj_cMw@mail.gmail.com/T/#me1b4a97adb119c25dc79826d49746216dd94bd26).

As mentioned in v1's discussion, this time v4l2-compliance has been run before
and after each patch to make sure no regressions are introduced. The latest
v4l2-compliance does find quite a few errors on the current mainline though, and
the second half of this series fixes several of them.

After this series the following v4l2-compliance failures remain:

* VIDIOC_(TRY_)ENCODER_CMD fails because there is no support for encoder
  commands. I have a patch fixing this but it depends on some extra refactoring
  introduced by the decoder series (that will follow this one), so it will be
  submitted along with it.
* VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT also fails because one cannot subscribe to
  the EOS event. This depends on encoder commands to be properly sent, so the
  fix will also follow.

Changes since v1:
* Checked that no regressions against v4l2-compliance were introduced,
* Fixed 9 failing v4l2-compliance tests,
* Removed 1 cleanup patch of contested utility,
* Carried Acked-bys and Reviewed-bys from mtk-vcodec maintainer.
