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.
