Subject: drm/amdgpu: do not disable SMU on vm reboot
Git-commit: 05cac1ae8ffbc5d835213ff2f9d7b8998c1f532f
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
For passthrough device, we do baco reset after 1st vm boot so
if we disable SMU on 1st VM shutdown baco reset will fail for
2nd vm boot.
