<p class="MsoNormal">Revert "drm/amd/display: Remove call to amdgpu_pm_compute_clocks"<br>
<br>
This reverts commit dcd473770e86517543691bdb227103d6c781cd0a.<br>
<br>
when display configuration changes, dc need to update the changes<br>
to powerplay, also need to trigger a power state task.<br>
amdgpu_pm_compute_clocks is the interface to set power state task<br>
either dpm enabled or powerplay enabled<br>
