mainboard/intel/saddlebrook: add support for Saddle Brook

Add initial files to support the Saddle Brook board. This board uses the
Skylake FSP 1.1 image and does not build without the FspUpdVpd.h file.
Most of the code has been taken carried over from kunimitsu with changes
done for Saddle Brook.

Saddle Brook is a reference board for Skylake SOC and has DDR4.

TEST=Build with uefi payload and boot to Linux 4.9 on CRB successfully.
