Disambiguate the former from the latter to fix the warning. Note that adding context qualifiers in the term is strictly necessary in order to make Sphinx happy.

This file has multiple acronyms that are not documented in the glossary. This commit introduces some missing acronyms to the AMD glossary documentation. The meaning of each acronym in this commit was extracted from code documentation available in the following files: - drivers/gpu/drm/amd/amdgpu/gfx_v7_0.c - drivers/gpu/drm/amd/include/amd_shared.h Changes since v1: - Expand acronym meanings based on Alex Deucher suggestions.
