Underclock/Overclock by default to avoid battery overheating:

min frequency is underclocked to 51mhz and max frequency is overclocked to 1.5ghz

With the current kernel setup the voltages need to be close to stock
to avoid spinlock but when gaming battery overheats.  This fixes that
and doesn't seem to affect performance at all.
