drm/radeon: don't set default clocks for SI when DPM is disabled
This is a partial revert of c6cf7777a32da874fabec4fd1c2a579f0ba4e4dd.
We need to take into account the clk voltage dependencies of the
board. Not doing so can lead to stability issues on certain
boards if the clks exceed the levels in the dep tables.
DPM already takes that into account, so for optimal performance,
use DPM.
