haswell: unify romstage logic
This commit pulls in all the common logic for romstage into the Haswell cpu directory. The bits specific to the mainboard still reside under their respective directories. The calling sequence bounces from the cpu directory to mainboard then back to the cpu directory. The reasoning is that Haswell systems use cache-as-ram for backing memory in romstage. The stack is used to allocate structures. However, now changes can be made to the romstage for Haswell and apply to all boards.
