      Fix exit to EFI firmware

      The current code for EFI grub_exit() calls grub_efi_fini() before
      returning to firmware. In the case of ARM, this leaves a timer
      event running which could lead to a firmware crash. This patch
      changes this so that grub_machine_fini() is called with a NORETURN
      flag. This allows machine-specific shutdown to happen as well
      as the shutdown done by grub_efi_fini().
