[U-Boot] [PATCH v3 06/12] x86: coreboot: Move coreboot-specific defines from coreboot.h to Kconfig

[Bin Meng]

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.

Changes in v3:
- Make coreboot options wrapped by TARGET_COREBOOT
- Remove these options from include/configs/coreboot.h for bisectability

Changes in v2:
- New patch to move coreboot specific defines from coreboot.h to Kconfig
