CONFIG_SYS_CBSIZE contains the buffer size for input for the console. The vast majority of platforms define them to some reasonable value (256, 512 or 1024 bytes), and it is quite annoying to repeat this definition for all platforms while it isn't really HW-related.
Therefore, let's provide a sane fallback value in config_fallbacks.h, so that platforms can rely on it instead of having to explicitly define it.
We use 1024 when KGDB is enabled, and 256 otherwise, which is what the majority of the platforms are doing.
