lib/coreboot_table: set type and size of framebuffer tag after fill_lb_framebuffer

When testing Ron's patch on qemu I found out that fill_lb_framebuffer
overwrites size and tag fields. We need either to fix/check all
fill_lb_framebuffer implementations or write tag/size after fill_lb_framebuffer.
I prefer later as it's more robust.
