I explained why I didn't delete this file in the changelog.

If this patch were applied whilst DEBUG_LL_UART_NONE still exists then
there are problems with oldconfig builds failing to compile (for the
same reason as the versatile stuff).

I hope at some point soon(ish) to have a patch series that moves all
four platforms across and trashes DEBUG_LL_UART_NONE. I'll respin this
patch as part of that (with the deleted file).
