drm/amdgpu/gfx11: Add Cleaner Shader Support for GFX11.0.1/11.0.4 GPUs
Enable the cleaner shader for additional GFX11.0.1/11.0.4 series GPUs to ensure data isolation among GPU tasks. The cleaner shader is tasked with clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps avoid data leakage and guarantees the accuracy of computational results. This update extends cleaner shader support to GFX11.0.1/11.0.4 GPUs, previously available for GFX11.0.3. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.
