Integrator and footbridge are the only platforms that would ever
actually work with VGA console because the others are all returning a
physical address rather than a virtual address. kirkwood, dove, mv78xx0,
and orion5x are all wrong. I'm not sure on shark. Seems to be a virtual
address, but it's not mapped.
So perhaps the correct fix is just to remove the initialization of
vga_base on all these platforms.
