nb/intel/haswell: Introduce option to not use MRC.bin
Introduce the `USE_NATIVE_RAMINIT` Kconfig option, which should allow
booting coreboot on Haswell mainboards without the need of the closed
source MRC.bin. For now, this option does not work at all; the needed
magic will be implemented in subsequent commits. Add a config file to
make sure the newly-introduced option gets build-tested.
