drm/amdkfd: only allow heavy-weight TLB flush on some ASICs for SVM too
The idea is from
commit a50fe7078035 ("drm/amdkfd: Only apply heavy-weight TLB flush on Aldebaran")
and
commit f61c40c0757a ("drm/amdkfd: enable heavy-weight TLB flush on Arcturus").
At the moment, heavy-weight TLB could cause problems on ASICs except
Aldebaran and Arcturus.
A simple hipMallocManaged/hipFree program could trigger this issue.
