Reapply "Revert "drm/amd: Skip power ungate during suspend for VPE""

Skipping power ungate exposed some scenarios that will fail
like below:

```
amdgpu: Register(0) [regVPEC_QUEUE_RESET_REQ] failed to reach value 0x00000000 != 0x00000001n
amdgpu 0000:c1:00.0: amdgpu: VPE queue reset failed
...
amdgpu: [drm] *ERROR* wait_for_completion_timeout timeout!
```

The underlying s2idle issue that prompted this commit is going to
be fixed in BIOS.
This reverts commit 2a6c826cfeedd7714611ac115371a959ead55bda.

This was lost in the 6.19 merge so reapply it.
