Added Live OC version 1.
When the OC value is changed, the changed bus and PLL frequencies are
properly accounted for on the next frequency change. Also on reboot the
proper sleep frequency scaled with the OC value is used.
Fixed bug in scaling of DRAM frequencies.
It is made sure that after wakeup from suspend for the next frequency
change the corresponding steps for both a changing pll and bus frequency
are performed.
When the GPU is active the minimum frequency is adjusted to the second
lowest frequency taking into account the current OC value.
The CPUfreq stats are only reset when CPU_FREQ_STAT is enabled in the
kernel config.
Refresh rate of DMC0 is not scaled with the OC value.
Modified 'Bring over sleep crash fix by Michael Huang<mike.g.huang@gmail.com>' for LiveOC
