drm/amd/pm: workaround for compute workload type on some skus

Browse Source 
commit 7ca302d488 upstream.

On smu 13.0.0, the compute workload type cannot be set on all the skus
due to some other problems. This workaround is to make sure compute workload type
can also run on some specific skus.

v2: keep the variable consistent
