drivers/emulation/qemu: Show splashscreen on bochs VGA
Show the coreboot bootsplash in qemu when running with bochs vga.
By default the framebuffer will be initialized in 800x600@32.
This can be overwriten by configuration.
The same code does not work on the cirrus vga, as it only shows
a white screen - more investigation will be required.
This was tested in 1280x1024 by setting CONFIG_DRIVERS_EMULATION_QEMU_BOCHS_{X,Y}RES
