In an attempt to make loglevels more visible (and therefore useful, hopefully), this patch adds a prefix indicating the log level to every line sent to an "interactive" console (such as a UART). If the code contains a `printk(BIOS_DEBUG, "This is a debug message!\n"), it will now show up as [DEBUG] This is a debug message! on the UART output. "Stored" consoles (such as in CBMEM) will get a similar but more space-efficient feature in a later CL.
