drm/amdgpu/gfx10: Refine Cleaner Shader for GFX10.1.10
[ Upstream commit d26625d034fb8d596f0488472969493fa02d03f3 ]
This patch updates the cleaner shader, which is responsible for
initializing GPU resources such as Local Data Share (LDS), Vector
General Purpose Registers (VGPRs), and Scalar General Purpose Registers
(SGPRs). Changes include adjustments to register clearing and shader
configuration.
- Updated GPU resource initialization addresses in the cleaner shader
from `be803080` to `be803000`.
- Simplified the logic in the SGPR clearing section, ensuring all SGPRs
are set to zero.
