haswell: enable cache-as-ram migration
The haswell code allows for vboot ramstage verification. However, that code path relies on accessing global cache-as-ram variables after cache-as-ram is torn down. In order to avoid that situation enable cache-as-ram migration. cbmemc_reinit() no longer needs to be called from romstage because it is invoked automatically by the cache-as-ram migration infrastructure.
