Useless forward declarations.
Actually its helpful in other patches. I was trying to avoid making too
many code movement in other patches to eliminate the forward
declarations. I guess I can fix in v7.

Sure, I will remove the check.

Boris,
I had your R-b in v6 and have kept it. The changes in this patch are
very minor. Let me know if you are okay with it - thank

Boris,
It may look confusing that we call PLATFORM_STATUS command to check the
current FW state even when we keep the state in psp->s
I just realized that this should be marked as "PATCH v6.1 13/38 ...". I
had some debug patch before this hence it was pushed below in the stack.

Boris,
I have tried to minimize the INIT -> SHUTDOWN transition by keeping state
information in sev_state variable. Since we INIT the platform during the
modprobe time hence we no longer need the kref count and init mutex.
Here are li
