describe all typical and use unevaluatedProperties to fix dtbs_check
warnings like:
arch/arm64/boot/dts/freescale/imx8qxp-ai_ml.dt.yaml: i2c@5a800000:
'assigned-clock-rates', 'assigned-clocks', 'clock-names', 'power-domains' do not match any of the regexes: 'pinctrl-[0-9]+'
arch/arm64/boot/dts/freescale/imx8qxp-colibri-eval-v3.dt.yaml: i2c@5a800000:
'touchscreen@2c' does not match any of the regexes: 'pinctrl-[0-9]+'
