Revert "FSP: Disable PSI link whenever FSP tells OPAL about impending…
… R/R" This reverts commit a4788a4. Above patch was added to handle host power down with FSP in R/R state. But FSP is not liking OPAL giving up PSI link early in R/R process. For FSP initiated R/R OPAL should wait until we get PSI interrupt. Hence reverting above commit. Also partially reverting commit e04a34a to make fsp_dpo_pending as global variable. We have made several improvement in the way we handle FSP communication and also in power down path. Now if host sends powerdown message when FSP in RR, OPAL return OPAL_BUSY_EVENT. Kernel will run poller() and retry power down message after sometime. So I think this patch will not have any side effect on power down path.
