In Xiaomi Poco F1 (qcom/sdm845-xiaomi-beryllium-ebbg.dts), the FocalTech
FT8719 touchscreen is integrally connected to the display panel
(EBBG FT8719) and thus should be power sequenced together with display
panel for proper functioning. Add the panel property which optionally
allows to link panel to the touchscreen.

SoB mismatch.

Please run scripts/checkpatch.pl and fix reported warnings. Then please
run 'scripts/checkpatch.pl --strict' 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.

So you just list all properties from touchscreen... no, use
unevaluatedProperties instead of additionalProperties.
