HV: trusty: refine secure_world_control

Browse Source 
Define Bitmap flag to indicate secure world's state:
    supported: 0(not supported), 1(supported)
    active:    0(inactive), 1(active)

Refine secure_world_memory:
    base_gpa_in_sos: base_gpa from SOS's view
    base_gpa_in_uos: base_gpa from UOS's view, this is the original base_gpa
                     allocated by bootloader.
    Recording above GPA is for usage of trusty EPT destroy and re-create.
    There is an assumption: the secure world's memory address is contiguous
    in both SOS and physical side.
