haswell: add CBMEM_MEMINFO table when initing RAM

Populate a memory_info struct with PEI and SPD data,
in order to inject the CBMEM_INFO table necessary to
populate a type17 SMBIOS table.

On Broadwell, this is done by the MRC binary, but the older
Haswell MRC binary doesn't populate the pei_data struct with
all the info needed, so we have to pull it from the SPD.

Some values are hardcoded based on platform specifications.
