Update coreboot + merge GM45 hybrid GPU patches

Also add power_on_after_fail to X200 and others (prevents the bug
where the system would boot when connecting the AC adapter)
(option in menuconfig to use CMOS/nvram settings is now enabled)

Also NetDCDC is now the default USB debug dongle used (compatible
with the BBB rev C).

Add two new methods for managing coreboot configs:
./build config corebootreplace
./build config corebootmodify

 				Libreboot is known to work on systems with only the Intel GPU, using native graphics initialization.
-				On systems with switchable graphics, it is believed that the ATI chip is used by default; coreboot
-				was tested with the native init and it didn't work, so the theory is that you have to disable
-				the ATI chip and make it use the Intel GPU instead (with native graphics), using the same method
-				as lenovobios. The other alternative is to implement native graphics initialization for the ATI chip
-				used on some models, but this is much harder (disabling the ATI chip in favour of Intel is likely much easier).

-				For now (unless you want to help make systems with switchable graphics work, where a display
-				is initialized for the Intel GPU), you should avoid systems with switchable graphics.
+				On systems with switchable graphics, the Intel GPU is used and the ATI GPU is disabled, so
+				native graphics initialization works all the same.
