	we currently have 2 fifo at comsole level one for input one for output
	we fill the output fifo before any console is registered and then
	empty it

	Now we introduce a new mecanism as in the kernel dmesg

	we will always fill the output kfifo with drivers output

	as in barebox we have 2 world

	device/drivers and applicaiotn (commands)

	so for now on drivers will have to use pr_xxx and dev_xxx and
	application will use printf

	dmesg will print the kfifo at any time

	we will extend this later with more control of what the drivers output
	on the console or just in the fifo

	This new eature is optionnal if dmes is disable we continue as before
