drm/amdgpu: Use mmhub inst_mask for gmc v12_1 vmhub setup

Browse source

gmc v12_1 currently derives the number of mmhub vmhubs
from the aid_mask when populating vmhubs_mask. This
breaks when mmhub is represented by mid and mmhub
inst_mask does not match the aid_mask.

Iterate over adev->mmhub.inst_mask instead so vmhubs_mask
reflects the discovered mmhub instances.
