Recently (qemu 2.2+) the qemu stdvga got a register to switch the vga
framebuffer endianness. This patch adds code to explicitly set the
endianness of the framebuffer. In most cases this has no effect as
the default is guest architecture endianness. It is needed though in
case a architecture supports both big and little endian, i.e. for
ppc64le.

DRM driver for (virtual) vga cards using the bochs dispi
interface, such as the qemu standard vga (qemu -vga std).
Don't bother supporting anything but 32bpp for now, even
though the virtual hardware is able to do that.
Known issue: mmap(/dev/fb0) doesn't work.
