drm/amdgpu: defer test IBs on the rings at boot (V3)
amdgpu_ib_ring_tests() runs test IB's on rings at boot
contributes to ~500 ms of amdgpu driver's boot time.
This patch defers it and ensures that its executed
in amdgpu_info_ioctl() if it wasn't scheduled.
V2: Use queue_delayed_work() & flush_delayed_work().
V3: removed usage of separate wq, ensure ib tests is
run before enabling clockgating.
