Subject: drm/amdgpu: Fix masking binary not operator on two mask operations
Currently the ! operator is incorrectly being used to flip bits on
mask values. Fix this by using the bit-wise ~ operator instead.
Addresses-Coverity: ("Logical vs. bitwise operator")
Fixes: 3c9a7b7d6e7520 ("drm/amdgpu: update mmhub mgcg&ls for mmhub_v2_3")
