drm/amdgpu/gfx10: Add Cleaner Shader Support for GFX10.3.x GPUs
Enable the cleaner shader for other GFX10.3.x series of GPUs to provide data isolation between GPU workloads. The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX10.3.x GPUs, previously available for GFX10.3.0. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.
