Subject: drivers: Replace set_vbe_mode_info_valid

Currently it's not possible to add multiple graphics driver into
one coreboot image. This patch series will fix this issue by providing
a single API that multiple graphics driver can use.

This is required for platforms that have two graphic cards, but
different graphic drivers, like Intel+Aspeed on server platforms or
Intel+Nvidia on consumer notebooks.

The goal is to remove duplicated fill_fb_framebuffer(), the advertisment
of multiple indepent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.

Replace set_vbe_mode_info_valid with fb_add_framebuffer_info or
fb_new_framebuffer_info_from_edid.
