[ Upstream commit 2ab4d0e74256fc49b7b270f63c1d1e47c2455abc ]
For SI/Kv, the power state is managed by function
amdgpu_pm_compute_clocks.
when dpm enabled, we should call amdgpu_pm_compute_clocks
to update current power state instand of set boot state.
this change can fix the oops when kfd driver was enabled on Kv.
