Subject: [PATCH 144/237] Fix exit back to EFI firmware
Arm/AArch64 machines set up a timer event which is not getting
canceled when returning to firmware. This is because grub_exit()
calls grub_efi_fini() instead of grub_machine_fini(). The latter
will shutdown the timer (and other machine-specific things) as
well as make the call to grub_efi_fini().
