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.
