Move the CG enablement out of delay worker thread.
1. CG/PG enablement are part of gpu hw ip initialize, we should
wait for them complete. otherwise, there are some potential conflicts,
for example, Suspend and CG enablement concurrently.
2. better run ib test after hw initialize completely. That is to say,
ib test should be after CG/PG enablement. otherwise, the test will
not cover the cg/pg/poweroff enable case.
