Subject: Revert "drm/amdkfd: only allow heavy-weight TLB flush on some ASICs
for SVM too"
Git-commit: 515d7cebc2e2d2b4f0a276d26f3b790a83cdfe06
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
This reverts commit 36bf93216ecbe399c40c5e0486f0f0e3a4afa69e.
It causes SVM regressions on Vega10 with XNACK-ON. Just revert it
at the moment.
