security/intel/stm: Make sure stm_resource_heap is consistent

When a parallel SMM relocation is being done, there is a good chance
that the value for stm_resource_heap is not consistent across processors.
Rather than holding (via a lock) processors until this value is set and
then flushing the cache so that all processors see the same value, this
solution moves the code such that all processors set it, thus maintaining
parallelism and keeping the code simple.
