include: add dedicated header for printf/printk

Including <stdio.h> for printf is a bit problematic, because it pulls in
other headers for <console.h>, which includes quite a few more headers
as well. To make it easier to share code between barebox and host tools
make <printk.h> the new minimal header for printf and move the extra
logging stuff into <linux/printk.h>.
