In a noninteractive environment barebox will be compiled without
command support. So move version_string to a seperate file which
is compiled unconditionally.
Also, display the banner when the simple console support is used.

commands/loadb.c doesn't build with CONFIG_CONSOLE_SIMPLE, because it uses
fprintf / for_each_console (which uses console_list).
Fix it by adding trivial implementations of both in console_simple.

Add a simple console layer which is not able to handle multiple
consoles for those who don't need it.
