Update Purism coreboot to 4.22.01-Purism-1. Signed-off-by: Jonathon Hall <jonathon.hall@puri.sm>
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.)

Interesting. So affects nv41/ns50 as well (librem 11 = GOP igfx) @daringer. Will review tomorrow! |

This includes various suspend fixes for Librem Mini v1/v2, support for latest hardware revision of Librem 14 (v1-02, new CPU stepping), and the new audio codec in the latest Librem 11 revision.
intel_iommu=igfx_offwas added to the Linux command line again for Librem 11, this is needed for framebuffer OS boot (e.g. memtest86+) on Librem 11 (which uses FSP GOP for graphics init, unlike other Librems which use libgfxinit). All the other coreboot config changes are just from updating to 4.22.01-Purism-1.
