Add constants for fast path resume copying
cache as ram does not usually cache the ram before it is up. Hence, if romstage.c backs up resume memory, the involved memcpy is always uncached. This makes resume very slow. On Sandybridge we copy the memory later, after enabling caching, and that allows us to resume in as little as 250ms.
