octeontx2-af: utilize hardware FLR support in SSO

commit a8e7de98bcc87f8d4e6c584c8c27a50b27d56146 from
git@git.assembla.com:cavium/WindRiver.linux.git

The CN10KA B0 and CN10KB SSO hardware now have the ability to carry out
certain steps of the software FLR routine. As a result, the kernel FLR
routine has been updated to utilize this newly enabled feature.

HW FLR performs five steps. It includes invalidating the cache of the
workslot, cleaning the prefetch entries within the workslot, emptying
all SSO queues, and writing reset values to the related registers.
