drm/amdgpu: Enhance Cleaner Shader Handling in GFX v9.0 Architecture v2 



This commit modifies the gfx_v9_0_ring_emit_cleaner_shader function
to use a switch statement for cleaner shader emission based on the
specific GFX IP version.

The function now distinguishes between different IP versions, using
PACKET3_RUN_CLEANER_SHADER_9_0 for the versions 9.0.1, 9.1.0,
9.2.1, 9.2.2, 9.3.0, and 9.4.0, while retaining
PACKET3_RUN_CLEANER_SHADER for version 9.4.2.

v2: Simplify logic (Alex).
