northbridge/intel/fsp_*: Remove legacy SoCs
* Remove FSP Sandy/Ivybrige which are unused. * Open Source implementation isn't final but good enough to replace FSP version. * For new ports use NORTHBRIDGE_INTEL_IVYBRIDGE and NORTHBRIDGE_INTEL_SANDYBRIDGE Change-Id: I7b6bc4bfdd0481c8fe5b2b3d8f8b2eb9aa3c3b9e Signed-off-by: Philipp Deppenwiese <zaolin.daisuki@gmail.com> Reviewed-on: https://review.coreboot.org/29402 Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
