config/coreboot-librem_11.config: intel_iommu=igfx_off on Heads cmdline
intel_iommu=igfx_off is needed on the Heads kernel command line for
memtest86+ to work.  Without this parameter, the screen blanks when
memtest86+ starts testing.

This is unique to Librem 11, probably because it is the only device
using FSP GOP for graphics init in coreboot.  (libgfxinit does not yet
support Jasper Lake.)
