serialio: Preserve Xen DebugOutputPort
xen_preinit() runs early and changes DebugOutputPort. qemu_preinit() runs
soon after. inb on DebugOutputPort doesn't work on Xen, so the check
will always fail and DebugOutputPort will be cleared to 0 disabling
output.
Quick exit the function when running on Xen to preserve the modified
DebugOutputPort.
