Payloads: Add U-Boot as a coreboot-payload
- Add Kconfig and Makefile options to use U-Boot as a payload.
- Add Kconfig option for extra cbfstool command line arguments.
- Add Kconfig & Makefile option to load the payload as a flat binary.
- Add u-boot directory to .gitignore.
This is currently working for X-86 only.
Graphics worked in U-Boot correctly by initializing the VBIOS and
setting up a console mode.
Tested in QEMU and on Minnowboard Max. Got into U-Boot, have not
booted an OS yet.
