soc/intel/broadwell: Consolidate SPD handling
Mainboards do not need to know about `pei_data` to tell northbridge code
where to find the SPD data. As done on Haswell, add the `mb_get_spd_map`
function and the `struct spd_info` type to retrieve SPD information from
mainboard code without having to use `pei_data` in said mainboard code.
Unlike Haswell MRC, Broadwell MRC uses all positions of the `spd_data`
array, not just the first. The placeholder SPD address for memory-down
seems to be different as well. Adapt the existing code to handle these
variations. Once complete, the abstraction layer for both MRC binaries
will have the same API.
