* @brief Switch vCPU state between Normal/Secure World.
*
* * Hypervisor uses the Secure Monitor Code (SMC) instruction to do
* the world switch
* * The hypervisor needs to save current world vCPU contexts, and load
* the next world vCPU contexts
* * Updates ``rdi``, ``rsi``, ``rdx``, ``rbx`` to next world vCPU contexts
* * The hypervisor uses this hypercall to do the world switch
* * The hypervisor needs to:
* * save current world vCPU contexts, and load the next world
* vCPU contexts
* * update ``rdi``, ``rsi``, ``rdx``, ``rbx`` to next world
* vCPU contexts
