VBE: Skip graphics mode setting for non-VGA devices 

This hit me when running the latest Qemu with coreboot:
First the graphics OPROM is running, then an iPXE OPROM.
The iPXE OPROM has no int10 support (obviously) so calling
vbe_set_graphics() wipes the framebuffer information from
the coreboot table.
