Save the pointer of efi_ctx in mi_drivers_addr field of multiboot structure and pass to hypervisor, not by saving in register RDX(the third default parameter in 64bit call function). With this method, we can be compatible with the original 32bit boot parameters passing method and no need to large the array size of boot_regs in hypervisor.
