drivers: Replace multiple fill_lb_framebuffer with single instance

Currently it's not possible to add multiple graphics drivers into
one coreboot image. This patch series will fix this issue by providing
a single API that multiple graphics drivers 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 independent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.

Replace all duplications of fill_fb_framebuffer and provide a single one
in edid_fill_fb.c. Should not change the current behaviour as still only
one graphic driver can be active at time.
