drm/amdgpu: fix MES GFX mask
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 <[email protected]> Cc: Alex Deucher <[email protected]> Acked-by: Christian König <[email protected]> Signed-off-by: Shashank Sharma <[email protected]> Signed-off-by: Arvind Yadav <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
