Subject: drm/amdgpu: use sjt mec fw on aldebaran for sriov
Git-commit: 1d32af4facd075542b26550e679ab53b5b8b5c5f
Patch-mainline: v6.1-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 jsc#PED-2849
The second jump table is required on live migration or mulitple VF
configuration on Aldebaran. With this implemented, the first level
jump table(hw used) will be same, mec fw internal will use the
second level jump table jump to the real functionality implementation.
so the different VF can load different version of MEC as long as
they support sjt
