ARM: HYP/non-sec: migrate stack The current code that switches into HYP mode doesn't bother to set up a stack for HYP mode. This doesn't work for EFI applications as they expect a usable stack. Fix this by migrating the stack pointer from SP_svc to SP_hyp while in Monitor mode. This restores the stack pointer when we drop into HYP mode.
