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.
