[PATCH AUTOSEL 4.18 47/56] drm/amdgpu: Update power state at the end of smu hw_init.

[Sasha Levin]

From: Rex Zhu <Rex.Zhu@xxxxxxx>

[ 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.
