x86: Drop the x86_fb driver

Browse source 
Now that we have a full VESA driver we may as well use that. We need to
support the VESA layer being set up by early start-up code or by

Turn on this option to enable a very simple driver which uses vesa
to discover the video mode and then provides a frame buffer for use
by U-Boot.
