Enable low-level debugging support for RZ/G1M (r8a7743). RZ/G1M uses SCIF0 for the debug console, like most of the R-Car Gen2 SoCs.
Thanks for your patch! While the recommended debug method these days is "earlycon", DEBUG_LL is indeed still useful to debug issues before earlycon is initialized. Let's hope you will never encounter such issues on arm64, which doesn't have DEBUG_LL per policy decision...

This line is becoming a bit long, and it'll only become worse in the future. What about "Kernel low-level debugging messages via SCIF0 on R-Car Gen2"? The full list of SoCs is still available in the extended help text.

when I'm talking to journalists I just say "programmer" or something like that.
