There are many places in the U-Boot source tree which refer to CONFIG_SYS_COREBOOT, CONFIG_CBMEM_CONSOLE and CONFIG_VIDEO_COREBOOT that is currently defined in coreboot.h. Move them to arch/x86/cpu/coreboot/Kconfig so that we can switch to board configuration file to build U-Boot later.

This target is used for running U-Boot on top of Coreboot. In

this case Coreboot does the early inititalisation, and U-Boot

takes over once the RAM, video and CPU are fully running.

U-Boot is loaded as a fallback payload from Coreboot, in
