drm/amdgpu: Check pmops for desired suspend state
commit 91e273712ab8dd8c31924ac7714b21e011137e98 upstream.
[Why]
User might change the suspend behaviour from OS.
[How]
Check with pm for target suspend state and set s0ix
flag only for s2idle state.
v2: User might change default suspend state, use target state
v3: squash in build fix
