[PATCH] drm/amdgpu: use sjt mec fw on aldebaran for sriov

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
