New hypercall: HC_SAVE_RESTORE_SWORLD_CTX In UOS S3 suspend path: trusty kernel driver will call this hypercall to require Hypervisor save context of secure world. In UOS S3 resume path: virtual firmware will call this hypercall to require Hypervisor restore context of secure world. New bit in secure_world_control.flag: ctx_saved: indicate whether cpu_context of secure world is saved.
