After dig more about async threads, I found dpm_prepare/complete phases need
them also.

dpm_prepare()

It will cause much time delaying due to d3_delay.
And I made one draft patch to implement the asynchronous threads for dpm_prepare(),
it is really save much time.

If you like it, I can prepare another series patches for dpm_prepare() and dpm_complete(),
thanks.
