[PATCH 1/2] libmm score and stubs

[Gedare Bloom]

Hi,

The approach we have taken so far with libmm is that it is "always on"
even if it is not supported by the BSP/CPU. In the cases that it is
not supported, the functions are nops that may have minimal effect on
runtime if users try to use the libmm. (Currently there is no API for
using libmm.)
