We could keep the kconfig select, so only one item is selectable, and
introduce a CONFIG_VGA_QEMU as option which builds a vgabios with
cirrus+bochs support & runtime hardware detection.

One wouldn't be able to build a pure cirrus / bochs bios then.  I don't
think this is an issue as I don't think they are used outside qemu.
bochs is sort-of paravirtual anyway, and I doubt anyone runs a cirrus
bios on non-virtual hardware ...
