drm/amdgpu: fix GFX10 missing CSIB set(v3)
still need to init csb even for SRIOV v2: drop init_pg() for gfx10 at all since PG and GFX off feature will be fully controled by RLC and SMU fw for gfx10 v3: drop the flush_gpu_tlb lines since we consider it is only usefull in emulation Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
