Only a 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 defconfigs since it is often
selected by default.

This patch limits this choice only to platforms which offer no other
means to use DEBUG_LL.
