drm/amdgpu: fix MES GFX mask
[ Upstream commit 9d3afcb7b9f950b9b7c58ceeeb9e71f3476e69ed ] Current MES GFX mask prevents FW to enable oversubscription. This patch does the following: - Fixes the mask values and adds a description for the same - Removes the central mask setup and makes it IP specific, as it would be different when the number of pipes and queues are different. v2: squash in fix from Shashank Cc: Christian König <Christian.Koenig@amd.com> Cc: Alex Deucher <alexander.deucher@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Shashank Sharma <shashank.sharma@amd.com> Signed-off-by: Arvind Yadav <arvind.yadav@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
