qemu: complete bochs dispi interface vga driver.
Ditch unused fb*.h files. Rename init.c (name is _way_ to generic) to bochs.c. Add proper bochs dispi interface detection and mode setup. Hook up coreboot framebuffer table initialization.

VGA driver for qemu emulated vga cards supporting
|

the bochs dispi interface. This includes
|
||||
standard vga, vmware svga and qxl. The default
|

vga (cirrus) is *not* supported, so you have to
|
||||
pick another one explicitly via 'qemu -vga $card'.
