Subject: [PATCH] drm/amdgpu/atomfirmware: fix vram_info fetching for renoir
Git-commit: d7a6634a4cfba073ff6a526cb4265d6e58ece234
Patch-mainline: v5.8-rc4
References: git-fixes

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.
