[En-Nut-Discussion] reclaiming PE0 and PE1 from uart0

Hello,

You don't need to redirect stdout, but you may not use it after 
commenting out the code at all. AFAIK there just was the discussion to 
create a NULL device to redirect stdout for debugging purpose.

If you don't register any UART device and correctly set the direction 
registers you may use these two pins for you own purpose.

Best regards,

Ole Reinhardt
