For power state 3 sclk and mclk corespond to Core Clk and Memory Clk.

In power state 2 sclk is 10 MHz lower, with power state 1 its 10 MHz higher
and in boot state its 100 MHz higher.

I don't know how the radeon DPM code figures the power state levels but
something is wrong here.

Can I force dpm into a power level at module load time? I suspect forcing into
state 3 should work.
