qemu: add bochs-display support
Use coreboot text mode emulation to also support the qemu bochs-display
device. This is a new display device supporting simple linear
framebuffers, using the bochs register interface. No support for legacy
vga (text modes, planar modes, cga modes, 8bpp palette modes all
dropped). The bochs interface is compatible with the qemu stdvga.
