Drop the u-boot patches which allowed building u-boot flashable to SPI. The board wiki already has links to flashing their own u-boot to SPI. It's a pain to update u-boot for us due to patches. The installation docs for the board will be updated to point to the board wiki for flashing u-boot for SPI. This also reduces our maintenance work and makes it easier to update u-boot.
