drm/amdgpu/atomfirmware: fix vram_info fetching for renoir

Browse Source 
commit d7a6634a4cfba073ff6a526cb4265d6e58ece234 upstream.

Renoir uses integrated_system_info table v12.  The table
has the same layout as v11 with respect to this data.  Just
reuse the existing code for v12 for stable.

Fixes incorrectly reported vram info in the driver output.
