    Provide support for setting up the framebuffer from EDID
    
    Add three functions to edid.c:
    
    void set_vbe_mode_info_valid(struct edid *edid, uintptr_t fb_addr)
    takes an edid and uintptr_t, and fills in a static lb_framebuffer struct
    as well as setting the static vbe_valid to 1 unless some problem
    is found in the edid. The intent here is that this could be called from
    the native graphics setup code on both ARM and x86.
    
    int vbe_mode_info_valid(void)
    returns value of the static vbe_valid.
    
    void fill_lb_framebuffer(struct lb_framebuffer *framebuffer)
    copies the static edid_fb to lb_framebuffer.
    
    There is now a common vbe.h in src/include, removed the two special ones.
    
    In general, graphics in coreboot is a mess, but graphics is always a
    mess.  We don't have a clean way to try two different ways to turn on
    a device and use the one that works. One battle at a time. Overall,
    things are much better.
    
    The best part: this code would also work for ARM, which also uses EDID.
