Add support for Sandybridge and Ivybridge using the Intel FSP.

"Intel® Firmware Support Package (Intel® FSP) provides key
programming information for initializing Intel® silicon and can be
easily integrated into a boot loader of the developer’s choice.
It is easy to adopt, scalable to design, reduces time-to-market, and
is economical to build."
