Rather than simply parking the R5 core in WFE after starting up ATF on A53 instead use SYSFW API to properly shut down the R5 CPU cores as well as associated timer resources that were pre-allocated. This allows software further downstream to properly and gracefully bring the R5 cores back online if desired.
