Only coreinfo title bar seen when loaded from GRUB
Using commit ab94ba30 (intel/common/block/itss: Extend itss_irq_init() to handle IOSF 1.0),
and building an image for the Lenovo X60t with GRUB as payload, and coreinfo as secondary
payload, loading coreinfo from GRUB with
chainloader (cbfsdisk)/img/coreinfo.elf, only
the green title bar can be seen. The rest stays black.
