[PATCH v2] dt-bindings: display: panel: Document the rotation property

[PATCH v2] dt-bindings: display: panel: Document the rotation property

[Luca Leonardo Scorcia]

The Jadard jd9365da-h3 driver already allows DRM to get the panel orientation
via the device tree rotation property (described in panel-common.yaml),
but it's currently not documented.
Describe it in the driver documentation to fix a dtbs_check error in
Xiaomi Mi Smart Clock x04g, where the panel is landscape-oriented.

v2: Review feedback: improved commit message to explain how the rotation
    property is used by the driver and why it's needed in the driver
    documentation.

Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):
https://elixir.bootlin.com/linux/v6.4-rc1/source/Documentation/process/submitting-patches.rst#L597

Please run scripts/checkpatch.pl on the patches and fix reported
warnings. After that, run also 'scripts/checkpatch.pl --strict' on the
patches and (probably) fix more warnings. Some warnings can be ignored,
especially from --strict run, but the code here looks like it needs a
fix. Feel free to get in touch if the warning is not clear.
