fix(rmmd/sve): enable/disable SVE/FPU for Realms This patch enable/disable SVE/FPU for Realms depending upon it's state in NS. When this feature is enabled, traps to EL3 on SVE/FPU access from Realms are disabled. However, RMM must ensure that the Realm <-> NS SVE/FPU registers are not corrupted by each other and Realms do not leak information to NS.
