drm/amdgpu: Update power state at the end of smu hw_init.
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.
