intel/fsp2_0: Add fsp2.1 shared stack feature support
FSP 2.1 implementation is adding features on top of fsp2_0.
One such feature is a shared stack implementation that requires
coreboot to allocate stack for fspm and then fsp uses the same
stack as coreboot. This implementation adds support for shared
stack feature.
