[PATCH] drm/amdgpu: Enable GFXOFF for Compute on GFX11 V2

[Ori Messinger]

GFXOFF was previously disabled as a temporary workaround for GFX11
due to issues in some compute applications.
This patch re-enables GFXOFF for GFX version 11.

V2: keep GFXOFF disabled on GFX11 if MES KIQ is below version 64.
