From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The ATI VGA device isn't a requisite for the Pegasos2 machine
because Linux only uses the serial console; see commit ba7e5ac18e7
("hw/ppc: Add emulation of Genesi/bPlan Pegasos II") for rationale.

Using the default devices we don't have any problem:

  $ qemu-system-ppc -M pegasos2
  qemu-system-ppc: standard VGA not available

But when trying to explicitly use the ATI device we get an error:

  $ qemu-system-ppc -M pegasos2 -vga none -bios pegasos2.rom -device ati-vga,romfile=
  qemu-system-ppc: -device ati-vga,romfile=: 'ati-vga' is not a valid device model name

Add it as an implicit Kconfig dependency.
