[PATCH 2/3] drm/amdgpu: add a forward declaration for struct amdgpu_iv_entry

[Alex Deucher]

To prevent:
warning: ‘struct amdgpu_iv_entry’ declared inside parameter list will not be visible outside of this definition or declaration

Fixes: 0f60e1036d85 ("drm/amdgpu: Modify the compilation failed problem when other ras blocks' .h include amdgpu_ras.h")
