[PATCH v4 3/5] ARM: Conceal DEBUG_LL_UART_NONE from unsupported platforms

[Daniel Thompson]

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 limit this choice only to platforms capable of supporting it.

 		  Say Y here if your platform doesn't provide a UART option
 		  above. This relies on your platform choosing the right UART
