Limit the workaround introduced by commit 31729e8c21ec ("drm/amd/pm: fixes
a random hang in S4 for SMU v13.0.4/11") to only run in the s4 path.

I tested this on SMU 13.0.4 for ~85 cycles with this script, BIOS 1.1.0.2a and
didn't observe any hangs.
```
#!/bin/sh
echo test_resume > /sys/power/disk
i=1
while [ : ]; do
echo "Starting cycle $i"
echo disk > /sys/power/state
echo "Ending cycle $i"
i=$((i+1))
sleep 5
done
```
