drm/amdgpu: reduce reset time

In multi container use case, reset time is important, so skip ring
tests and cp halt wait during ip suspending for reset as they are
going to fail and cost more time on reset

v2: add a hang flag to indicate the reset comes from a job timeout,
skip ring test and cp halt wait in this case

v3: move hang flag to adev
