Only boot 32-bit u-boot from grub, 64 from seabios

Browse Source 
For some reason, 32-bit U-Boot only works when executed from
GRUB, but not SeaBIOS; 64-bit U-Boot only works from SeaBIOS!

This will have to be investigated. Standalone U-Boot, where
U-Boot is the primary payload, has not yet been tested in
Libreboot, and will not be provided for some time due to
stability concerns. More testing is needed!
