-machine graphics=off is the usual way to tell the firmware or the OS that the
user wants a serial console. The pseries machine however does not support
this, and never adds the stdout-path node to the device tree if a VGA device
is provided. This is in addition to the other magic behavior of VGA devices,
which is to add a keyboard and mouse to the default USB bus.
Split spapr->has_graphics in two variables so that the two behaviors can be
separated: the USB devices remains the same, but the stdout-path is added
even with "-device VGA -machine graphics=off".
