KGPE-D16: update patch set (also update coreboot and vboot)
Also contains other fixes from coreboot, like:
* 551cff0 Derive lvds_dual_channel from EDID timings.
^ makes single/dual channel LVDS selection on GM45 automatic
* 26fc544 lenovo/t60: Enable native intel gfx init.
^ was being maintained in libreboot, now upstreamed so not needed
Framebuffer mode was disabled for the KGPE-D16, because only
text-mode works at the moment.
