lib/coreboot_table: Show splashscreen in lb_table_init

Browse Source 
Every vga init implementation needs to cache the framebuffer state
to be able to fill the lb_framebuffer struct later on in the
fill_lb_framebuffer call. Showing the bootsplash afterwards
guarantees to have the same interface into all the vga drivers.

This is by far from ideal, as it only allows for a single driver at
compile-time and should be adapted in the future.

It was tested on the wip razer blade stealth using vgabios @ 1280x1024
and also in Qemu @ 1280x1024.
By default the qemu framebuffer will be initialized in 800x600@32.
This can be overwriten by configuration by setting
CONFIG_DRIVERS_EMULATION_QEMU_BOCHS_{X,Y}RES .
