coreboot/e6400: support nvidia models
The same ROM images that you flash on Intel GPU variants, are now flashed on Nvidia models. The same ROM will work on both. If an Intel GPU variant is present, libgfxinit is used, and the VGA ROM is used if an Nvidia GPU variant; however, release ROMs will scrub the nvidia option ROM, so release ROMs will only work on Intel GPUs unless you run the blobutil inject command. I decided to no longer have this under WIP, but to put it in master. The issue with it pertains to video drivers, which is not Libreboot's problem. Nouveau crashes under Linux, so use "nomodeset" if it does. The "nv" drivers in BSD systems work very well. The nvidia model of E6400 isn't recommended for other reasons, namely: poor thermal cooling (thermal pad on the GPU) and that Nvidia GPU doesn't get very good performance on any libre drivers anyway. The Intel GPU variant is better, in terms of power efficiency and software support; the intel variant also works with native graphics initialisation in coreboot. This board port already only enables SeaBIOS, which will simply execute the VGA ROM. Blobutil already supports reading the config, detecting that a VGA ROM is needed, because that part of the WIP E6400 branch was already merged in lbmk master.
