Rasmus Villemoes 04a20ca5dc common/console.c: prevent pre-console buffer contents from being added to itself 
I do not have any non-serial output devices, so a
print_pre_console_buffer(PRE_CONSOLE_FLUSHPOINT2_EVERYTHING_BUT_SERIAL)
does nothing for me.

However, I was manually inspected the pre-console buffer using md.b,
and I noticed that the early part of it was repeated. The reason is
that the first call of print_pre_console_buffer(), from
console_init_f(), ends up invoking puts() with the contents of the
buffer at that point, and puts() at that point ends up in the else
branch of

	if (gd->flags & GD_FLG_DEVINIT) {
		/* Send to the standard output */
		fputs(stdout, s);
	} else {
		/* Send directly to the handler */
		pre_console_puts(s);
		serial_puts(s);
	}

so indeed the contents is added again.

That can be somewhat confusing (both when reading the buffer manually,
but also if it did actually come out on some device). So disable all
use of the pre-console buffer while print_pre_console_buffer() is
emitting it.
