'-device VGA' maps to '-vga std'
'-device cirrus-vga' maps to '-vga cirrus'
'-device qxl-vga' maps to '-vga qxl'
(there is also '-device qxl' for secondary devices)
'-device vmware-svga' maps to '-vga vmware'
For the primary video device, we try to use 0x2 slot for matching
old qemu. If the 0x2 slot is allocated already, the addr property
of new video device could help for using any available slot.
If there is no -device option for old qemu, we keep using -vga for
primary device.
If particular one of above four VGA devices doesn't exist, we
switch to use -vga to generate video commandline. In this case,
the 0:0:2.0 address must not be used by previous PCI device.
For primary video device of xen type, there is no
corresponding arg to -device, we still leave the handling to -vga.
