mb/starlabs/starbook: Add CFR option to use native panel resolution

For boards for which set the 'Fixed Mode at boot' flag in the VBT, add
a CFR option to boot using the native panel resolution, rather than
a fixed/scaled video mode. This option selects between two VBT files:
one with the 'fixed mode' flag enabled, and one with it disabled.

This feature is mainly a workaround to a GNOME-related bug which
causes the creation of a 2nd display at the boot resolution. This
2nd display being a lower/different resolution than the native
panel resolution causes severe flickering/artifacting rendering
the display unusable unless this 2nd phantom display is disabled
on every boot
