Merge the different coreboot table strapping ID structures into one because they're really just all the same, and I want to add more. Make the signature of the board_id() function return a uint32_t because that's also what goes in the coreboot table. Add a printk to the generic code handling strapping IDs in ramstage so that not every individual mainboard implementation needs its own print. (In turn, remove one such print from fsp1_1 code because it's in the way of my next patch.)
