Remove extraneous assigned-clock* from media/i2c/* schemas.

assigned-clock and assigned-clock-parent assume that there is a clock that
can be assigned and/or a clock parent that similarly can be assigned by
firmware which may not always be the case.

The sensor properties themselves should not mandate assigned-clock* as a
result.

Changes in v3:
- Updates commit log with more description of why we are removing
  assigned-clock from the properties - Laurent
- Drops assigned-clocks from the examples too.
  assigned-clock in examples has the example quality as status="okay" - Laurent
- Link to v2: https://lore.kernel.org/r/20241025-b4-linux-next-202041004-i2c-media-yaml-fixes-v2-1-1b4535174a5a@linaro.org

v2:

- Changes series name was: media: i2c: Cleanup assigned-clocks and endpoint: properties: unevaluatedProperties: false
  Dropping the second patch in the series means the title changes too - bod
- Drops unevaluatedProperties -> additionalProperties change
  There is no clear consensus on this right now.
- Adds Reviewed-by and Acked-by as indicated to patch #1 Laurent, Krzysztof 
- Link to v1: https://lore.kernel.org/r/20241012-b4-linux-next-202041004-i2c-media-yaml-fixes-v1-0-a2bb12a1796d@linaro.org

v1:

On a recent schema submission I did what most well adjusted schema writers
do and tried to find a base file to work from to copy/paste and forget.

Confusingly/predictably I received feedback to remove or alter several of
the properties included in my devious copy/paste plan.

The first bit of feedback was that assigned-clock-* was to be dropped.
Removing assigned-clock-* as assigned-clock-* is a core property which
doesn't need to be listed in a schema.

The second bit of feedback landed on use of additionalProperties:false
along with enumeration of all required endpoint properties instead of an
implied list of valid properties from unevaluatedProperties:false.

Link: https://lore.kernel.org/linux-media/20241010-b4-master-24-11-25-ov08x40-v6-0-cf966e34e685@linaro.org

This series removes the assigned-clock-* from upstream sensor property
schemas and applies additionalProperities:false to properties: endpoint:.

A few missing properties: or required: are added to the schemas based on
output of DT checkers.

The one new DT complaint I didn't fix with the move to
additionalProperties: false is:

/home/deckard/Development/qualcomm/qlt-kernel-tools/qlt-kernel/build/x1e80100-crd_qlt_integration/arch/arm64/boot/dts/renesas/r8a774c0-ek874-mipi-2.1.dtb: imx219@10: port:endpoint: 'remote-endpoint' is a required property

Since this appears to be some sort of temporary/commented thing upstream
which I don't know the provenance of.
