The changes to support vram_usagebyfirmware v2.2 changed the behavior
to explicitly match 2.1 for everything older rather than just using it
by default. If the version is 2.2 or newer, use the 2.2 parsing, for
everything else, use the 2.1 parsing. This restores the previous
behavior for tables that didn't explicitly match 2.1.
Fixes: 4864f2ee9ee2 ("drm/amdgpu: add vram reservation based on vram_usagebyfirmware_v2_2")
