tanaro: Disable display support in defconfig
We don't want to handle the display timings in u-boot as well, and start the display with the kernel bootlogo instead.
Dear all, On Thursday, 4th September 2025, we will test the new disaster recovery environment. A disaster recovery test will take place between 4:00 PM and 6:00 PM CEST. Please refrain from making any changes, as they will be lost. Once testing is complete, the production environment will be restored. Thank you for your understanding.
