drm/amdgpu: add bitmask to iterate vmhubs
As the layout of VMHUB definition has been changed to cover multiple
XCD/AID case, the original num_vmhubs is not appropriate to do vmhub
iteration any more.
Drop num_vmhubs and introduce vmhubs_mask instead.
v2: switch to the new VMHUB layout
v3: use DECLARE_BITMAP to define vmhubs_mask
