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.
