Replaces NVDIMM flush sequence with CCS
The current design relies on the power control logic to put the nvdimm
into STR. There have been several defects opened on the nvdimm failing
to save due to STR not entered but no indication of the function failing
to execute. Therefore, the decision has been made to leverage CCS to issue
STR and assert RESETn. This gives us full control of what goes onto the
bus and not have to worry about STR getting exit due to unwanted mainline
traffic.
The same CCS sequence has already been exercised numerous times on AC
powerloss path.
