drm/amdgpu/dm: Resume short HPD IRQs before resuming MST topology

Browse source

Since we're going to be reprobing the entire topology state on resume
now using sideband transactions, we need to ensure that we actually have
short HPD irqs enabled before calling drm_dp_mst_topology_mgr_resume().
So, do that.
