sending csib command when system resumes
from S3
Previously the CSIB command pocket was sent to GFX block while amdgpu driver
loading or S3 resuming time all the time.
As the CP protocol required, the CSIB is not needed to send again while GC is
not powered down while resuming from aborted S3 suspend
