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.

-Subject: [PATCH 133/146] mainboard/asus/kgpe-d16: Limit HT speed to 2.6GHz
-
-The CPU <--> CPU HT wiring on this board has only been validated
-to 2.6GHz. While higher frequencies appear to function initially,
-and in fact function when only one CPU package is installed, dual
-CPU package systems will lock up after around 6 - 12 hours of uptime
-due to presumed HT link errors at the higher (>= 2.8GHz) HT clocks.
-
-If applications are not being used that stress the coherent fabric,
-then the uptime before hang may be much longer. Users attempting
-to overclock the HT links are advised to "burn in test" the HT links
-by running memtester locked to a node with no local memory installed.
