fsp_broadwell_de: Enable early write access to the SPI flash

If VBOOT is used on a mainboard based on fsp_broadwell_de then VBOOT
needs to be able to write to its NV data which may be stored on the SPI
flash. Enable write access to the SPI flash on SoC level. If the
mainboard does not use VBOOT the linker will drop the extra code. The
benefit is that this code is at least compiled and therefore build
tested with fsp_broadwell_de.
