dualroot: add chain of trust for Platform owned SPs
For dualroot CoT there are two sets of SP certificates, one owned by Silicon Provider(SiP) and other owned by Platform. Each certificate can have a maximum of 4 SPs. This patch reduces the number of SiP owned SPs from 8 to 4 and adds the remaining 4 to Plat owned SP. Plat owned SP certificate is signed using Platform RoT key and protected against anti-rollback using the Non-trusted Non-volatile counter.
