Convert binding doc colibri-vf50-ts.txt to yaml. Additional change: - add ref touchscreen.yaml. - remove standard pinctrl properties. Fix below warning: arch/arm64/boot/dts/freescale/imx8qm-apalis-eval.dtb: /touchscreen: failed to match any schema with compatible: ['toradex,vf50-touchscreen'] Reviewed-by: Rob Herring (Arm) <robh@kernel.org> Signed-off-by: Frank Li <Frank.Li@nxp.com> Link: https://lore.kernel.org/r/20240819142434.311760-1-Frank.Li@nxp.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
