lib/edid_fill_fb: Support multiple framebuffers
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 and Aspeed on server platforms or Intel and Nvidia on consumer notebooks. The goals are to remove duplicated fill_fb_framebuffer(), to advertise multiple independent framebuffers in coreboot tables, and better runtime/build time graphic configuration options. Add an implementation in edid_fill_fb that supports registering multiple framebuffers, each with its own configuration. As the current code is only compiled for a single graphics driver there's no change in functionality.
