Part of dmesg with power states

The problem is as follows. On r600, dynpm selects power state 1 and switches
between clock modes to upclock / downclock. One can see that power state 1 is a
performance power state, thus it does not include a low-power clock mode. In my
case, it would be preferable for dynpm to use power state 2. Ideally, users
should be able to select between low-power dynpm and performance dynpm.
