mb/intel/shadowwmountain: Enable CSE Lite SKU for shadowmountain

During the initial phases, the development and validation teams have to
deal with both Consumer SKU and Lite SKU firmware. Having the support for
CSE Lite enabled by default in coreboot helps in integrating both the SKUs.
With this we only have to interchange the CSE region in the full BIOS image
without having to worry about Kconfigs. Eases the build and integration
flow.
