Only a very small handful of platforms support DEBUG_LL_UART_NONE but it lurks in the menus of every single platform config ready to break the build. This is an especial problem for defconfig/oldconfig since it is often selected by default.
This patch solves the problem by removing this option. Any platforms still depending upon this option must be migrated.
