drm/amdgpu/gfx10: Enable cleaner shader for GFX10.1.1/10.1.2 GPUs

Enable the cleaner shader for GFX10.1.1/10.1.2 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 GFX10.1.1/10.1.2 GPUs,
previously available for GFX10.1.10. It enhances security by clearing
GPU memory between processes and maintains a consistent GPU state across
KGD and KFD workloads.
