Set console loglevel to a lower value to avoid tty spam
Set console loglevel to a lower value to avoid tty spam

Currently a mass of debug\error\etc messages from drivers errors\etc
spam to tty* - this totally blocks possibility to connect and debug with
tty*

We should set console_loglevel to a lower value, so the screen isn't
littered by kernel messages. Also these messages break the look of
fuelmenu (which, currently, has own printk setting code).
