Revert "Remove sandybridge and ivybridge FSP code path"

Please don't remove chipsets and mainboards without discussion and input
from the owners. Someone was asking about cougar canyon 2 just a couple
of weeks ago - there's obviously still interest.

This reverts commit fb50124d22014742b6990a95df87a7a828e891b6.
