mainboard/asus/kgpe-d16: Update NB VDD upper voltage limit 

Certain older Opteron processors use a higher (+1.2V) northbridge
voltage.  The existing code assumed the use of +1.1V northbridge
voltages and threw an alert when the older Opterons were installed.

Update the permissible NB voltage range to include both the 1.1V
and 1.2V Opteron processors.
